HI, I'm trying to learn my first symptoms: Often i get over interested of my work. Or i can start some "hobby" project which i get too much involved. This all feels to me very obvious and normal behavior. One common thing is that soon my wife will say that "I'm inside my brains" - just like in depression but positive way...

So If you can get feedback from close people, they might notice it much sooner than you.

I can't really stop myself before symptoms become too obvious, (i don't sleep etc...)
