They are just random. Like I wake up with intense racing thoughts which last a few hours (I don't know I lose track of time). There's nothing physical about them (unlike anxiety symptoms: racing heart, etc.) They've stopped after I increased my gabapentin. (Don't know exactly what gabapentin does.)

I had a Dr. 20 yrs ago that asked me if things felt "speeded up" and I told him "yes". He diagnosed me bipolar.
