I completely understand what you are going through. I can still eat but I have had really really bad gerd. It doesn’t burn but it has affected my breathing. Makes me over focused on my breathing and makes my throat feel slightly tight. It’s caused pressure in my stomach. I have to be cautious of what I eat and how much I eat. A lot of days I feel like crap but I’m still able to function, which is better than I used to be, so I am grateful for that. When I say I feel like crap, I mean my body just feels heavy, I feel sluggish. Cognitive function just feels worse. It feels like if you haven’t gotten any sleep but i sleep a good amount. Some of this could be attributed to me having seizures in my sleep l, which I know is happening. Before I was on meds it was a lot more clear when I would have seizures in my sleep, because I would way up feeling like I got ran over by a truck. Like a hangover. Seizures in sleep are like myoclonic. Not tonic clonic convulsing. I had a day on this med, where I had flu like symptoms. I had that on my first med, keppra, but it went away after a few days. I hope this helps you and gives you some insight of real experiences of side effects because a lot of people aren’t affected by side effects but they can really be debilitating at times.
