We are so full of chemistry. Darn glands :-) What you may want to check out is why you think you need to get so much done? Instead of racing up the mountain of work - take slower and easier steps to congratulate yourself after each step is done. I've been there too - get 10 things done now now now. Then for a few hours after - nothing to do. You could do something really strange - you could penalize yourself when you get too much done. Meaning - you may be penalizing yourself (in your head) for not doing enough - but to keep yourself balanced, try penalizing yourself for doing too much - then you could possibly find some kind of balance in the middle. Just a thought.

As I read more about psych issues and learn "what we're made of" - hormones and neurotransmitters like Dopamine, Serotonin, Adrenalin, Cortisol, Tosterone, Etc... Lots of stuff that can go out of balance. Once you get out of balance, you feel sluggish or manic or whatever. I think the best thing to do is start with talking it over with your family doctor - then maybe a referral to a psychiatrist to consider looking at your medications + normal diet. Diet itself can make you manic for a while (high carbs.) followed by a drop in energy. Reminds me of kids on sugar. Anyone on sugar can act differently - as well as anyone on an imbalance of stuff in their brains and bodies.

Lately, when I'm feeling stressed out or tired, I try to check myself thinking "what could be out of balance right now?" Turns out it has helped me from getting mad at simple things I'd do - like make a mistake or drop something or instead getting upset I almost start laughing at things lately. There are times I'd feel manic too - usually after I eat well (good foods, not high carbs) - best feeling I had when I ate a lot of vegetables a year ago and lost weight (which I've added back on lately).
