Long time since ive been on here. My opinion is that your HTPA is way shutdown!
Some people run HCG while they are cycleing to keep FLSH - LH up and the HTPA.. Ive never done it before, but i know what your talking about
I had similar effects when i was running a winstrol only cycle "i know stupid" woke up from sleeping 12hours still feeling totaly tired and after 4-5hours taking a nap.. was like able to take 2-3naps a day
eyes where hard to keep open ect! my experience is that the reason for the body to sleep that much is to try to return to homostatis... Body recovers best while resting / sleeping
so my advice would be: Shoot some HCG, get on some support supps "triazole" love that, bump up your diet and increase your kcal intake! vitamins minerals ect. gonna take some time
