Mainly in my thought process and speech patterns.

I begin to find I can't focus on just one thing. Even when doing a single task, lets say driving, I can't just focus on that. I often find that I'm lost in my thoughts. I snap out of it and realized I've been driving for 20 minutes and haven't been paying any attention to the road. I'm not really sure how I even got there or where I am for a second.

Also I can't stop talking. I get to telling stories or drawing out simple explainations into 5 minute speeches. I talk very rapidly to the point a stumble over words and sometimes stutter. I don't let the other person get a word in edgewise in a casual conversation and I tell people things they dont need to know. It gets to the point the other person gets annoyed and stops paying attention, which infuriates me for some reason.

Also I see a rapid increase in risky/unsafe/unwise behavior. Sleep is usually lacking because I have so much on my mind to do and feel the need to get it all done right now. Sleeping and eating become an afterthought
