I was originally taking 12.5 mg at bed time as needed and it helped me gets a good nights rest. It also made me feel a lot calmer when I would wake up. Since the doc eventually wants me off the klonopin she decided to add 50mg of extended release seroquel. The first day I thought it was the magic pill- so calming. The second day I felt panicky and heart was racing. Is this normal ? She told me to try is for at least four days but itís not calming me at all.
