I switched from paxil to mylan bupropion, (paxil i had civid nightmares, nightsweats and slept 15 hours a day) the first and second day I felt fine. The third day I had dizziness and felt a bit off. Now he fourth day I found myself as parinoid, anxious, tears rolling down my face for no reason and getting irritable. I just don't feel like myself. Does anybody feel like this so soon?
