Welcome.

I was diagnosed a few months ago and am Bipolar I...formerly thought II but they'd never seen me manic...now they have.
I know what you mean about impulse control. For the past 2 days I've had very little when it comes to shopping. But I normally hate shopping! I also say and do things that later make me feel embarrassed then I call myself names and say negative things afterward.
It sucks. Don't blame yourself, just try to make amends when you're feeling better. Also, I agree with Vickie...meds alteration/change sounds in order. The lethargy/zombie thing you're describing is how I felt on Seroquel. They switched me to Abilify and I'm feeling much better. Still manic, but oh well, not depressed and sleeping most of the day. I'm also on Lamictal and Wellbutrin.
Hope you'll call you're p-doc and have something changed soon.
Feel free to share any time. Everyone I've met on this forum is very nice and understanding.
