Hey Hog,
I did some winny after many years away from gear and those first couple of weeks for me were tough. I had trouble sleeping and was worried all the time, although I had nothing to be worried about.
The good news was that I got some great results and my body did adjust to them, in fact i am taking the last of my winny today which I have been on for 6 weeks @50mgs per day along with a test cyp base.
peace
