I didn't get any negative effects from going up to 75 mg, it's been a week since my last panic attack, I haven't Google'd anything either! It could be just in my head but I already feel better.
I have real trouble getting out of bed in the morning though, and days seem to fly by. but I'd take that over anxiety and panic disorder any day.
I'm going to talk to my doctor about stopping my Xanax if I keep feeling better, I feel like I don't need it any more. I currently take 0.25 mg before bed and used to take it during panic attacks.
If any of you are out there like me, dead scared of taking Anti-depressants. Give it a try, seriously.
