I've had way more depressed stages than manic, but when I do go into these phases this is what results:

-Too much energy
-Increased racing thoughts (more than usual)
-The urge to be EXTREMELY social
-I talk to everyone and anyone and will get super personal
-I tend to have the strong urge to become inebriated
-Hypersexuality
-A feeling of anxiety and restlessness
-Insomnia
-Extreme impulse
-I basically just don't give a d*** what I do

Granted, it isn't as extreme as it was years ago, but still the same symptoms.
