Here's my brief background: I was diagnosed with anxiety and depression 4 years ago and along with it, I have severe acid reflux as well. It's been a month since my psychiatrist stopped my medications. My physician had suggested I take pantoprazole dsr to manage my acid reflux. So my problem is I have started feeling sleepiness and tired all the time and I feel nauseated. Some days I feel well but most of the days I feel very unwell. I exactly do not know which doctor should I visit or what should I do. Can you please provide me some suggestions?
