"i used methamphetamine when it first hit the street in the early 1980&#039;s and stopped on april 10, 2011. within days i developed chronic fragmented insomnia in which i was unable to sleep for more than 45 to 75 minutes at a time. attempting to avoid prescription anything, i tried every herb and supplement from valerian root to melatonin with very little improvement. after almost two years i became desperate and willing to try anything so i asked the doctor for help and was prescribed temazepam. now i get at least 4 hours of solid sleep and 4-1/2 to 5-1/2 hours of total sleep each night. i am a bit comatose in the morning for the first 30 to 60 minutes after waking even with coffee. the sleep walking is a bit unnerving though."
