hi everyone, i have not posted for a while as i felt i was managing my panic/anxiety ok with the help of sertraline and counselling. for the last week though i have been waking up in the early hours feeling very nervous and shaky, like tummy is full of butterflies and body is buzzing, i do not feel the same as panic attacks before but don't know what is causing this any ideas. not been having bad dreams and then once i am up for a while it seems to go away, especially after i have had sertraline. ? need higher dose on 100mg x
