I started taking it 16 days ... Ist day I sleep for 12 hours every night and have felt a little better but had a full blown panic attack today and am not feeling the relief I expected. Do I need to be more patient or should I be concerned that it isn't working for me because I still am having episodes 16 days in? I started on 15 mg for the first 4 days and have been on 30 mg for the past 12 days.
