I have never done any sort of illegal drugs in my life - but the day after I got my CPAP machine in 2001, I said "this must be what being on crystal meth is like". So his comparison is not out of line. You feel THAT much better/energetic/etc. I had no proper REM sleep for 4 years (the sleep study said I never slept for more than 30 seconds at a time), and then with the CPAP machine, I slept a solid 12 hours. Just imagine how much better you would feel after that - and give the guy a break for comparing it to coke.
