I had this issue a little over 2 months ago, and I feel like it still hasn't gotten any better. I was taking 300mg for over 6 months, and I constantly felt shaky, get irritated easily, felt anxious, and have sweaty palms. I've been on 150mg for almost 2 months, and it seems like nothing has changed. I graduated from college, so it's not like I have anything causing me stress? I like how this gives me energy, I just wish there was a way to counteract these side effects. Did anyone else experience this? What did you take or switch to to help out with it?
