Hey Robert,

IMHO, I think we should flow with nature, sleep at night, be awake in the day. When I get out of sync with it then I feel really weird and anxious.

Also, you're working a 70hour week, and I expect your sleep in the day isn't very decent: so you're probably knackered. A tired brain isn't good!

huge hugs and I hope you feel better soon. (sorry I couldnt have been more helpful in my post!) xx
