That doesnt sound overly dramatic to me. Sometimes being on too many meds can make us feel crappy, so the change may make you feel a lot better after the withdrawls wear off. It shouldnt take more than 2 weeks. I've done it dozens of times, without needing to go to hospital, it sucks but you can get through it. I found having a spew bag near by at all times was essential, drinking a lot of water, eating when I could - healthy as I could, having a lot of distractions, keeping a journal and using prn medication if needed. I tried to sleep a lot, it passes the time. Not all withdrawls are that bad so make sure you arnt psycing yourself up to have a bad time as that will just make things more difficult.
