I am feeling very strange and I'm starting to think it's due to coming off the perphenazine last week. I think I may have to go back on it, I'm having nausea, shakiness, anxiety, paranoia. That may also be the reason for the diarrhea for a couple days. It may be why I've been having panic attacks every night the past few days too. I just took a 4mg tablet of it, then over the next few days I'm going to build back up to 8mg, (my doctor said I can take it again if I need to)
