asleep by 1am and having 4.1/2 hours - i count you as a lucky one!
ive had my fair share of insomnia. ive had two serious bouts in my life and i dont get it for a couple of days, more like a couple of years at a time. prescribed sleeping tablets without a doubt will help you at night, but i could not function in the day eventually.
ive said this loads of times on this site, but nelsons noctura tablets really helped me. they are homeopathic, rather than herbal sleep aid. take 2, four hours before bed, and 2 when you go to bed. you cant feel them, they taste of sugar but they worked for me and i swear im one of the worst insomniacs i know!
