Air passage symptoms and conditions

This is the 3rd time I have been on Wellbutrin. Once in 1999, then in 2004, and just started taking it again 3 months ago. The first two times I took it I had joint pain and a lot of muscle inflammation. This go around is different... Just recently, within the past few weeks, I started breaking out with hives, after taking it with no problems for three months! Started on my head and progressively got worse. I break out all over my body, head, legs, back, hands, etc. For some reason it seems to happen more frequently when I lay down in my bed to go to sleep (weird!) One other scary side affect is, I frequently stop breathing when I start to fall asleep, and wake up gasping for air. Has anyone else experienced this?
Since I had never experienced problems with hives the first few times I was on Wellbutrin, I didn't think it was the medication causing the hives. So, I cut my dose in half (50mg/day). The hives didn't go away, so I stopped taking it all together 3 days ago, but still continue to get hives. Does anyone know how long it takes to get it out of your system?

Overall I'm feeling much more positive, capable of doing things, better emotional assessment and judgement. One side effect, though, is my breathing. I feel a slight tightness in my chest, almost light wheezing, but not exactly, and I feel like I've got to cough lightly to clear my air passage. Has anyone experienced this? Any insights are appreciated.

I started taking Advair about two years ago. The Doctors say I have COPD,and I was given Advair to help me breath. Since I started taking this drug I have developed cronic pain in my legs,arms and sholders, weaknes in my intire body, numbness in hands, cramps in legs,feet,hands and sometimes in upper body .I have a problem sleeping, nervousness,hoarseness. I have no quality of life any more. I loved gardening but cannot do any of that any more. Walking in my home is a chore now. I have told my Doctor but he seems not to believe me. Maybe we need to go to school to learn how to treat our illnesses. I hope some one will investigate this drug and its side effects. There has to be another drug to help open our air passage ways to help us breath. Peggy
