"i have had sleep problems for twenty years now due to pressure of work &amp; probably a predispostion to insomnia. have used various sleep aids benzodiazepines, diphenhydramine, etc. i am affected by both difficulty going to sleep &amp; staying asleep. recent reports concerning sleep aids &amp; alzheimers put me off using. melatonin not implicated as far as i know so i have turned back to that!! dosage 6mg slow release one hour before bedtime. as on previous occasions it is mild with no noticeable side effects. worth a try!"
