<<Disclaimer: Verify this information before applying it to your situation.>> Hi, Barb in Ohio wondered if reduction in sleep requirement is due to getting older or the gf diet. For several years I needed to sleep ALL weekend, most weekends, and 8hrs (minimum) each night during the week (and I did not feel well). When I was very ill I would sleep (as if under general anaesthetic) for 12 - 16 hours per day, for months. I'm on a gf diet for five months now and 8 hrs sleep every night are sufficient (and I feel very well). I'm 36 years old so I think that age is unlikely to be a factor in my case.
