"i am 75 year old and have taken clonazepam 0.5 mg tablet for about 4 years for restless legs and insomnia. i take 1/2 of the tablet every night, along with vitamin d and magnesium &amp; aleve for arthritis pain. it has been very effective for me, it lets me sleep with no hangover but i do have vivid dreams every night, not nightmares though.. on occasion i have taken a full tablet but i keep them cut in half and usually only need the 1/2 dose. my new doctor is taking me off of them and putting me on mirapex for restless legs and melatonin to sleep. melatonin has never helped before but i will try again."
