Not having a good day already, I'm due to fly n holiday Tuesday morning and the anxiety has started already. I really don't understand it as I've flown lots of times before and it's never been an issue. It all started last night when I had a huge panic attack and ended up taking 5mg diazepam which my dr prescribed for the flight, I've never taken it before and it made me feel awful :-( and I now feel my fluxetine isn't working. I've woke up this morning feeling awful, all shakey, feeling sick and a headache and just feel generally awful.
