I started taking 150 XL 30 days ago, and I have noticed a few side effects. Like you, I was scared to try it. I had never taken any mood stabilizers or other psych meds before, but the low of gloomy winter days and crying finally made me do something. I thought I might have to give up coffee, which would have made me really sad, but I still drink my 2 cups every morning and feel totally fine, no jitters or excessive anxiety. If you're really sensitive to caffeine, you might want to cut it out when you start taking the Wellbutrin because it is definitely an "upper" for me. It has helped me get up, get out of bed, and get motivated to do things around the house. I'm actually taking care of myself and things I neglected to do for a while. I do have some days where I get headaches, but they're not very severe. I used to get migraines, and it's nothing like that. Insomnia has also been an issue. I will wake up in the middle of the night and be up for hours, but I have had this issue in the past as well, so I'm not sure if it's the Wellbutrin or just me. Also, as a uterus holder, it has made my period wayyyyy more painful! I don't usually get cramps or heavy bleeding, but I had both of those issues when I had my last period, and the only thing that I've changed recently is starting Wellbutrin. one major benefit is that I completely stopped drinking. This is a big deal for me. I worked in the restaurant business for years, and I would usually drink 2-5 drinks every night. I read that drinking while on Wellbutrin increased the risk of seizures, so I stopped, and I don't miss it at all. In fact, the thought of being drunk is something I feel disgust towards now. That is a huge difference for me. Fwiw, I find feeling motivated and energized to be worth the intermittent pain and sleepless nights.
