Desired results symptoms and conditions

I was prescribed Wellbutrin by my Ob/Gyn for S.A.D. (Seasonal Affective Disorder). The actual prescription allowed for generic and I started out taking 150mg of Bupropion a day. I felt like this was too much as during the day I was fine, but at night I would get very jittery and almost manic. So I called to find out about cutting it down to 75 mg, just once a day instead of twice. I was fine but noticed in the last few days my neck and chin started itching really badly. Yesterday I made the connection that the hives appeared approximately one to two hours after I took my one dose. I took my meds at around 1:00 p.m. and by 5:30 I noticed fairly predominant hives on my neck and chin. I treated it with hydrocortisone cream and it went away. Today I did not take any meds at all and I have no hives or itching of any kind. I am sure it is from the meds because absolutely nothing else has changed in my life (soap, foods, etc.). If there is anything else that gives the same desired results for S.A.D. but without all the crazy side effects please let me know so I can ask my doctor. Thanks.

I am 59 years old Asian male and have gone through six angioplasty and have seven stents in all three arteries in the year 02-03. No heart attack so far. I am taking 10 mg of Lipitor and can not tolerate 20 mg or higher strength because pain in the knee, thigh and leg increases. I tried to reduce my cholesterol by changing food, weight reduction and 40 minutes of tread mill at 5 mph, 5 days a week. I did not get the desired results i.e. keeping LDL below 70.
Since liver makes 80 % of cholesterol, I have to take 10 mg of Lipitor and tolerate the minor side effects. With change in diet, exercise, weight reduction, and 10 mg of Lipitor, I am able to reduce my total cholesterol from 247 to 116, LDL from 164 to 62 and increase HDL from 32 to 42.

Age: 47
Male-176lbs- 5' 9", overall excellent health.
Lipitor used over 2 years. Started with 10mg ended at 40mg to get desired results. 6 month blood work.
Side effects: Started at around 18-24 months. Felt like I had aged 10 years.
1.Felt like I has sand in my shoulder joints, could not throw a ball or raise arms above head.
2. Knee joints ache, could not squat down and get back up.
3. Extreme touch sensitivity to shin area above ankle. Difficulty sleeping.
4. Increased lack of ability to concentrate.
Stopped all Lipitor- Took around 6 weeks for joint pain to ease. 3 months back to normal.
Doctor tried Prevastatin- Same side effects as Lipitor.
Nice to have my life back.
Hope this helps- Brent
