I googled restful sleep so that I may be able to more properly deal with my chronic fatigue. The search came up with glycine and ZMA. I take the glycine and seems to work well mixed with a little Klonopin and Inderol/propranolol. I'm sure everyone is different so you may have to try and adjust it yourself. I started off taking only an 1/8 to 1/4 tsp glycine and 5 mg melatonin before bed without the other medicines and it seemed to also work well. If you wake during the night you can take another 1/8 tsp of glycine. I'm not a doctor so use your best judgement on this. Thanks.
