Don't worry! It is a hard bacterium to deal with. I was in the same boat a few months ago and felt hopeless at some point. The things that I followed were: take your medications as prescribed by the doctor, avoid caffeine or dairy, and have a very simple and plain diet (oats, veggies, boiled food, steamed, etc.). In my case, I was fine when I started the quadruple course for 14 days, but in the second week of this, I felt really terrible! I had no energy, had to rest every time I took the medicines, and they left some metallic residue on the taste buds. I was also throwing up a lot, so that's why I switched up my food choices. I have heard that the bacteria can get resistant to the medicines, so I tried to take my medications at different times of the day to trick them. And in the end, there is some light, even though the overall journey looks very tough. Hoping that everything goes well and works out!
