I have anxiety disorder but was given too high a dosage for me (100mg) which made me feel like I was in a fog...like I was really high on something. Also gave me major insomnia, stomach cramps and dry mouth. But when my dose was reduced to 50 mg, I felt much better. The anxiety is gone, and I feel like I am more "present", and better able to focus. My only negative side effects now seem to be a bit of paranoia (nothing serious) and a big appetite increase. The benefits are definitely outweighing the negatives.
