I do have that same problem and tried the same things. However, I found on a recent trip for a family reunion that if I took a hot shower before bed I relaxed me enough to go right to sleep. I did wake a couple hours later because the couple in the next room were expressing their carnal pleasures loudly.
I've just published chapter seven of Undercovers Detective. I would love your feedback on this story. I'm planning on ten chapters at least. If you haven't read one yet, I've included links. I hope you like them.
