Cattle prod 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?

Was put on Cymbalta after taking Prozac because I just did not feel "myself". While on the Cymbalta, I could not sleep at all and my psych tried Rozarem first, then Lunesta and then Ambien CR instead of taking me off the Cymbalta! Still did not keep me asleep. Within two weeks of using this drug (with the Cymbalta) I had a "medicinal black-out" - one of the side effects. I apparently thought my husband was walking the dogs and went out garage where I fell down steps, cracking two ribs. I walked in and told my husband I think I fell. He thought I was drunk and just put me to bed. I have absolutely no memory of any of this. Also had three pychotic breaks while taking the Cymbalta and finally took myself off of it. This is day 17 of withdrawal. I don't hate anyone enough to wish this on them. You have brain zaps (like a cattle prod), vertigo, pain in your joints and muscles that make you scream. I would not let anyone go on either of these drugs, ever! I just went to a specialist yesterday in St. Louis that told me all my symptoms were related to my Mitral Valve Prolapse and that I have MVP Syndrome and I'm not crazy at all. For all of you suffering from panic attacks, depression, eating disorders, heart pain, insomnia, etc., have yourself tested for MVP. I have known I've had this heart defect since my late teens and I'm now 48. No one has ever told me that these symptoms are related to my prolapse just psychological issues!!
