Wellbutrin and antidepressant

I have been on Bupropion SR 300mg. since May 2007. Within the last 4-6 weeks may hair has been coming out by the hand full when I wash it. Alot of it is in my hair brush, vacuum cleaner, and on my clothes. I have used special shampoos and vitamins with no luck. I called the pharmacy and was told this was not a side effect of the medication. Funny they haven't heard, according to all the post I have read on the internet. My question is has anyone else experienced this type of loss after being on the medication for 6 months or longer? And if you stayed on it, or any other antidepressant, did the hair loss stop and grow back. I was also told that if it were to be a side effect of the medication it would have happened before now, and maybe I should have other test performed. I have already had blood work for thyroid and it came back normal. Love the medication!
Helps with more energy! Hate the hair loss! HELP!!!

Have been taking Wellbutrin 400mg for about 3 years.

For depression, it is wonderful. I have never in my life had so much relief from major depression.

For side effects, I don't like it. I have a very strong itching sensation on my chest. This never goes away, but I can deal with it. I get a lot of tension, but that is not so bad. The really scary part is the terrible headaches. I think they are getting worse, and NOTHING gets rid of them except skipping the Wellbutrin.

Right now I am worried because I can't function with the headaches, and I can't function with the depression. I know there is no other antidepressant that works as well as Wellbutrin.

Like many people I have seen online, I have broken out in large, itchy hives 3-4 weeks into starting on Wellbutrin. I am really bummed becasue I love the drug and it is the 1st one I have been on that hasnt effected my libido (the reason I stopped the other ones). Please, someone out there tell me these go away and I dont have to stop taking it and jump to yet ANOTHER antidepressant??? I am willing to wait a few weeks if thats what it takes!
