I really don't have any sleep problems any more. I don't eat night shade vegetables (potatoes, tomatoes, peppers, or smoke tobacco) and I also rub some epsom lotion on the inside of my arms before turning off the light. I've had pn since 1999 so I do know all about sleepless nights. I think the whole routine of eliminating certain foods, using the benfotiamine and L-theamine, as well as the epsom lotion is working for me.
