Absolutely! With a high that sends me buzzing for only half a day, coupled with inability to concentrate or get things done, I really don't feel good about myself.
Then comes the crash - well a sort of crash - the fuel runs out and my engine splutters, my feelings are dented. I'm not suicidal at this point, just not swinging from the chandeliers. Then a few hours later (probably about bed time) something clears the blockage in my fuel pipe, and my engine races to 18 000rpm again.
Where is that feel good high I was so hoping for? That little bit of hypomania that makes me feel like king of the world again. I seem to miss it completely.
Sigh!
