Seems to be working... I figured after a few weeks, delaying a dose by 12 hours wouldn't make a huge difference. I'm definitely getting further through the day without dropping like a fly! Although I seem to remember that does wear off eventually anyway. I had a near panic attack yesterday, but there was an extreme situation which provoked it and I think without Fluoxetine it would have been a full-on meltdown! Yay for drugs!
