Contentment symptoms and conditions

I have been taking the generic form of Wellbutrin (social anxiety with a touch of ADHD) for just over six months and as much as I hate to admit it, I believe that the bad is finally, convincingly, outweighing the good.
The good things that came along with 150mg of the SR every morning at 11:00: Weight loss (but only after an initial one month period of eating every form or carbohydrate I could find), it seems to brighten the whites of my otherwise cloudy eyes, helped me maintain conversations with people that I would have normally cut off early, and possibly--but only possibly--helps me focus (although the hyper focus that I used to get via the ADHD is gone. Completely. Non-existent.)
Which brings me to the bad: This goes against most of what I've read other people experience on Wellbutrin but lethargy has set in. And it feels like it's here to stay. It's not really a sedated lethargy but more of a false contentment that everything is just fine the way it is. No progression, no improvement, and looking to the future is almost impossible through the fog. I too, during the first two or three weeks, had the speedy, productive reaction to the medication. But that has subsided. Next, hair loss has become a concern. I'm in my thirties and it could be just how it goes but I truly doubt it. Mild constipation may seem bearable but I miss regularity more than I have time to describe. Ringing in the ears. Impaired memory. Confusion. Forgetfulness to a fault. Mild hives on the back. Irritability. A marked shortness of breath. After one month on Wellbutrin, I could barely run a mile on the treadmill when I've been accustomed to flying through three to five with ease. I feel weak, vulnerable even. Working out has therefore fallen to the wayside. And last, but probably the worst, this medication has seemed to cultivate a serious craving for other drugs. I can't explain it but I can't take it anymore either.
Like most people on a medication, I have read numerous posts and some people share some of my concerns but mostly, it seems that the people who report in are the speedy folks on day two or week two. That is, in my opinion, only a bit helpful, since these effects are usually short-lived. Wellbutrin started out with promise but while parts of me look into the mirror and see an improvement, underneath it all, I know that it is purely a nicely dressed form of prescribed avoidance.
I haven't posted this to discourage anyone. If it works for you--great. Really. But I also haven't read anyone's experience that matched my own so I figured it might help someone who is going through any of the same. Good luck.

I went on Paxil CR (12.5 mg) because of constant panic attacks that lasted for about 1 month. I was so anxious for this period of time that I rapidly started losing weight, broke out in hives and eventually couldn't trust myself to function normally in common situations (i.e. work, driving, etc.). I was on it for 1 year and noticed a significant difference within 2 weeks. The panic attacks stopped, I returned to my normal weight and remained there, and I had an overall feeling of contentment. I went off of it 2 months ago because it was making me feel too content and I was starting to make bad choices (some anxiety is a good thing). I just want all of you to know that it can be used as a tool to help you get back on track, it should never be the solution. I had a few side effects coming off of it (dizziness, feeling electric-like shocks), but have not had any panic attacks or unusual anxiety. It sounds as if a lot of the side effects listed here could be a symptom of anxiety itself. If you make changes to your lifestyle, and are confident in your decision, you can leave Paxil behind.
