Wellbutrin SR and nausea

I have been using Wellbutrin SR 200mg Twice Daily (maximum dose for my weight) for a couple of years now and cannot report ANY side effects. I don't get any stomach aches or nausea -- even if I take it on an empty stomach. I don't get any light-headedness, it doesn't make me tired or hyper, I have no trouble sleeping, and my sex drive is unaffected. I do have migraines/headaches, but I've had those since I was a child and I take other medicine for that. I'm also on Zoloft. I have tried a number of depression/anxiety drugs over the years and Wellbutrin is my favorite BY FAR!

Besides nausea, I also experience a caffeine-like effect from Wellbutrin. I forgot to put that in my last post - I guess I've been taking the pill so long I forgot about this effect. It is not a problem for me unless I take the pill late in the day - then I have trouble falling asleep. I just make sure to take the pill before noon, and then I avoid the insomnia. I do the same with coffee or anything with caffeine in it.
So here is my final side effects list, after 3+ yrs of taking the drug:
1. Nausea
2. Insomnia if taken late in the day, caffeine-like effect
3. Appetite suppression (may be temporary?), weight loss
4. Inability to enjoy smoking cigarettes
Hope this helps.

Nausea is the only side effect I have noticed after taking 300 mg of Wellbutrin for over three years now. The nausea is worst in the morning, after I take the pill. My stomach feels very acid, like I just drank a pot of coffee with no breakfast. It usually gets better if I eat something, although not always.
For the first few years, I also experienced decreased appetite - no complaints there! I lost weight, but this year I regained it. Not sure if the appetite suppression effect wore off, or if this year has just been really stressful for me.
I also found it impossible to smoke cigarettes - they tasted nasty. Another good side effect for me.
Overall, Wellbutrin has helped me with depression and social anxiety. Best of all, I have absolutely no sexual side effects, unlike with every other antidepressant I have tried.

Headaches, nausea, and I'm not able to sleep through the night...I literally will wake up every hour IF I get to sleep. I am seriously thinking of just stopping it completely and dealing with the depression.
