Wellbutrin and chest pains

Hello.

I am 26 years old with no health issues at all. Wanted to quit smoking, Dr. prescribed me bupropion/Wellbutron SR 150 mg.
I was instructed to take 1 pill a day for 2 weeks. After 2 weeks I set my quit date and then take 2 pills a day. (300mg)
For the first 2 weeks...I really didnt feel like myself. Felt like I can snap at one moment and then calm the next moment. ok, not such a big deal.

During week 3 I quit smoking and increased the dosage to 2 pills a day as instructed. I quit on Saturday, July 16th 2006. On Tuesday i started off with my regionals itching like crazy! I wasnt sure why this was happeneing so i put some anti itch cream and helped some what. I would just keep breaking out with the same bad itch anyway. Then...Wednesday, July 19th I woke up 2:00 AM with real bad chest pains and I was itching all over the place. From my head, neck, arms to my back and front of my body and basically had rashes all over the place.
They would disappear from one spot and appear in a different spot. I then started researching all over the internet about te side effects and I did find a ton of people expereincing the same things. From 2 AM i couldnt go back to sleep because of the pain in my chest and the HORRIBLE ITCHING and rashes.
I went ot the ER around 10:00 AM and stood there till about 5:30 PM. When I was in the ER i started breaking out even worse. My right eye was closing shut and my right hand became so itchy and swollen it looked like i broke my hand.
They quickly gave me a shot of Benadryl and some steroid with it and after about 30-60 minutes... the swelling started going away. They didnt find any realtionship from the Wellbutrin and my chest pain and the itchingness which i didnt understand.

Anyway, i still have some rashes breaking out...I have been using Benadryl which will control it a little bit but then I switched over to Claritin because i couldnt stand feeling like a walking Zombie from the Benadryl.

I am still researching and waiting for my Dr to come back to figure out how I can get rid of the itchy rash breakouts. I also feel just mild pain in my chest about once or twice a day for about 10 minutes.

If anyone knows anything that can help me...I would appreciate it.

thanks.

been on welbutrin XL for 4 days now. If I feel anything at all, it's very subtle. Well I can say that I have noticed a mild sore throat since day 1. This may be unrelated however. I notice some people stating "On the 1st day, so and so, then on the 2nd day, so and so" I was under the impression that it would take a minimum of 1 to 2 weeks before any FX were noticed. I guess everybodies different though. I was 1st on Lexapro, took it for 6 weeks and it did nothing at all for me. I might as well been taking Flintstone vitamins. So 4 days ago started with the Welbutrin XL after turning down the option to go on Paxil. After all the negative horror stories I've heard about Paxil, you couldn't make me try it. I've got high hopes for the Welbutrin XL, and hope I recieve the benefit of it's use and not the hair loss and other ill FX.
