First pill I took I noticed a stimulant effect. It increased wakefulness. Appetite was gone for 3 days but returned after 7 days on it. I think it's increasing my anxiety because of its stimulant properties. One thing I've noticed though is that face-to-face conversations are slightly easier. My voice tends to stay firm, I am more calmer and in control, but general anxiety is increased. I feel more anxiety in open-spaces. The "people are watching me" and scrutinizing feelings are higher. I also took a caffeine pill earlier today and this magnified the anxiety even more, which makes me think the stimulant effect is causing it. I've only been on this for about 13 days, but I don't think this drug is all that great.
