I was diagnosed RLS, have very difficult to falling sleep. I've been taking Gabapentin 900mg and Levodopa, but it seems that it's wearing off and I don't want to increase more. Gabapentin is supposed to help sleep but not helping me at all. My average sleep duration is 4 hours. However, my neologist Doctor doesn't prescribe me any sleeping medication because of side effect like dementia. If you have data for taking sleeping medications and dementia, I'd like to have it.
