Weed usually makes anxiety worse, at least for me it did.
SSRIs and alike do have a tendency to make anxiety worse at first, and have some crappy side effects too, but it gets better after about a month or 2 when your body adjust to it.
Usually a DR will prescribe you a mild sedative "benzo" or buspar to counteract the side effects during the break in period.
It also matter what brand name, or generic you get "the DRs will tell you it doesnt" but it does, Ive noticed that when I changed where I get my generic prozac, I get all these stomach cramps and stuff now, so now I have to change back..or suck it up and pay 144.00 per prescription of Name brand.
Maybe gas x would help?
Have you ever been checked for GERD or any stomach problems before?
also...i wanted to add that i was reading up on anxiety medications and supposedly in some people the medications can actually intensify your symptoms and i'm worried that may be the case for me because in places like california where medical marijuana is legal they will prescribe it for anxiety and in my case, smoking weed actually makes my anxiety much worse so i dunno..
