Wellbutrin may still be working, but not giving you the kind of "high" you described in the beginning. Instead of adding another medication, you might try working on the the everyday problems in a new way, maybe with the help of a therapist,maybe on your own. If you want some help with that, go to www.masteringstress.com.
Higher doses will not give you that same high, nor will lexapro.
The doc is right dude. Wellbutrin isn't going to give you the "high" you got in the beginning after months of taking it, just like anything else. If you want to feel high all the time, smoke a joint every day or take Klonopen. But if you want to deal with the problem at hand, see a psych and/or go to that web site the MD gave.
Sounds to me like you're basing your stress and anxiety level on pills, and not the problem at hand. That's not healthy at all. You didn't indicate any anxiety/depressive problems, so why are you complaining about the medication not working? No wonder why you're doc was puzzled...med's like Wellbutrin are not made to make people "high"...
I appreciate your response, although I am not sure I think it was what I was looking for...I have a happy marriage...and I have a blessed life.I have tried a therapist with the sex drive thing, and they only offered medication....back then I didn't want to try Psychiatric drugs...but I have since learned more about them. My "stress" is mainly putting up with my 5 year old's ways sometimes, and the daily routines/chores/ and not enough time to get things done, you know. Anyways, I am trying to find out why the Wellbutrin stopped working and how I can retrieve the great benefits I had in the beggining. Anyone ever hear of this or know a better route/medication?
