I notice the bright colors too when I'm manic/hypomanic. I also eat more and weigh a little bit more. The only time I forget to eat is if I'm drinking too much coffee. A big No-No, I realize.

I don't see the harm in a bit of hypomania, provided it doesn't become full blown mania. I'd enjoy it while it lasts and watch it carefully for signs that it's changing. Of course I'm not a doctor, so listen to them, not me. I'm just saying, that's the time when you can enjoy life and get things done.

But you know yourself and your body best. Take care of you.
