i feel like this now and its horrible so i do know how he feels, actually i feel like the air is hot and getting heavier all around my body and it feels like its tryiing to snuff out my phisical being so im definately feeling depersonalization 15 hours in and you think it would just be physical but its pretty bad mentally i was up to 10 a day or sometimes 12 so 60 is alot but dont know i can relate to what your saying cause im feeling it now!
The crawing out of your skin feeling can get pretty strong that it may feel hot to the body or he could be having hot flashes. 60 pills a day is alot, so his withdrawal is going to be much stronger and last longer than someone coming off 6 -10 day. His nerves are trying to adjust back to normal, i still felt bad after one month coming off a long battle with lortab 10-500 and i was on methadone at the time.
As the physical pains have passed so will these feelings, congrats on both of you getting clean.
I'm afraid I don't know about that... I never experienced it.
Hopefully someone will see your post who might be able to shed some light on this...
good luck to you and your friend,
