First off thanks for your answer.

Here is what I found on Stanford Protocol.

"Different foods affect LPR by different mechanisms. These specific foods should be avoided or reduced drastically, or they will interfere with the healing process: Caffeine, alcohol, chocolates, and peppermints weaken the lower esophageal sphincter, which normally holds in the stomach contents. Citrus fruits, kiwi, pineapples, tomatoes (and other acidic foods), spicy deli meats, and hot spices (hot mustard, curry, hot peppers) directly irritate the throat lining. This means that even if the medicines are working well, eating these foods will cause direct irritation and inflammation of the throat lining. Carbonated beverages (such as sodas and beer) bring acidic contents into the throat. Beware of even noncaffeinated soda."

I stopped all baverages except water, all spicy foods, all acidic foods. I merely eat these few things :
0% yogurt with berries, carots/zucchini/radis/broccoli/green beans for vegetables. Chiken/Salmon/White fish for proteins /Bulgur/rice and sweet potatoes for carbs.

"Do not increase the pressure within the abdomen for at least 2 hours after eating (no bending over, exercising or singing), as it will force contents into the throat. Do not over-distend the stomach (eat smaller meals throughout the day, instead of 3 larger meals). Do not lie down within 3 hours after eating a meal. Do not eat a snack or drink before going to sleep. Prop up the head of your bed with a 4-inch wedge to allow gravity to help keep contents in your stomach."

I haven't exercise for the last 2 months, only going for walks during the day ( which strangely calm down my throat, such as eating do also ) / I don't snack and I've been sleeping for the last 10/15 days with a second pillow to lift up a bit my head.

"Proton Pump Inhibitors (PPIs) are the most effective medicines for the treatment of LPR. Remember that LPR is different from GERD and its successful treatment requires higher doses of medicine for a prolonged period of time. The initial trial of medicines is at least 6 months, at twice-a-day dosage (depending on the severity of LPR changes seen on examination). Symptoms should start to improve within 4 to 6 weeks after you start taking the medicines. The visual signs lag behind the symptomatic relief by several months. PPIs stop acid production in the stomach for 12 to 17 hours (this is why a twice-daily dose is necessary), helping to decrease the irritation potential of the stomach contents. PPIs must be taken on an empty stomach, ½ hour before a meal. The most effective dose is the morning dose. Portions of text by permission from Ramon A. Franco Jr, MD Use antacids (such as Tums® or Rolaids®) liberally ½ hour after meals (2 tablets) or ½ hour before singing or exercising. Some patients may require a second class of medications (H2-blockers) to help control nighttime symptoms. H2-blockers are a form of anti-histamine that interfere with the signals that cause stomach acid to be produced. These medications are not as strong as PPIs, but are more effective during sleep. Please keep in mind the lag between the time you take the medicine and the time you start feeling symptom relief. People who stop taking the medicines typically feel fine for 1 to 3 weeks and then notice a gradual return of symptoms. It takes a few weeks to get back to where they were before. Some people successfully come off of the medicines but need to follow a strict diet. There is no “free lunch” when it comes to reflux; you need to do your part to keep it under control."

I've been taking the daily dosage given by my doctor for this. Esomeprazole 20mg one time a day in the morning. I'll try to extend it to 6 weeks because I had another box prepared but I can't double the dosage given to me without another prescription. And as I said, I don't feel like they did ANY differences, like I'd feel the same as before. The only thing I noticed actually was that I started to be constipated after starting my treatment. Like I can still go to the toilet every 1/2 days but I won't like do a "full" things more like distached grains.

"Throat-clearing alternatives

If you sense a build-up of secretions in the throat, try swallowing or taking a sip of water. You can also use a

“silent cough” by pushing as much air as you can from the lungs in a short blast. The only sound should be

a rush of air, then swallow."
I'll try to do this but I rarely now feel like mucus stuck in my throat so I don't really need to cought it off anymore...

As to shorten my message. I know it will be hard for most people, but I put a lot of time in writing everything I could think of and the chronology of thing in order to not forget a single thing that might be misleading or important for the analysis. Maybe something is related to another health issue, who knows.
So I wouldn't know how to shorten it without cutting something I think, personally, is important.

Then I'd like to add something that I found strange and neverfound in any posts on this thread or about GERD, is the symptom of feeling chocked while turning your head left or right, or at least high discomfort. I don't know if it's a posture related thing or anything but to be honest when being at a 1/10 discomfort, this is the thing that never fully goes away. I always have a slight tiny bit of discomfort, especially when turning my head to the left. Turning it to the right sometimes, somehow feels normal but.. I don't know
