I have been taking tylenol pm or the generic equate brand of it off and on for a couple of years (maybe two or three nights in a row). But for the last 3 to 4 month's it's been every night. So, I ran out about three days ago and now I am feeling depressed, stomach burning and aching and have diarrea about an hour after I eat. I also am having some unclarity in thinking? Is this a withdrawal sympton possibly?
