My cure that worked for me is a teaspoon of Bicarbonate of soda in a quarter glass of water at 7pm and the same measure again at 9pm. I go to bed at 11pm. This guaranteed me 6 hours uninterrupted sleep.The only drawback is slight constipation or hard stools and quite thirsty upon waking up. No caffeine produce during the afternoon too.
