@sleepy0 I am tired just reading your post! I have trouble getting back to sleep if I get up as morning is approaching (bathroom call, or to take medication) and I have trouble falling asleep if I have anything on my mind, or know I have a very busy day the next day. I take melatonin but frankly, I am not sure it helps. I do occasionally take 1/2 of a generic Benedryl tablet at bedtime, and that does help. I presume your doctor's suggestion to not take that was more to not take it on a regular basis, or are there other reasons also? Thankfully I do not have sleep apnea.
I hope you are getting enough sleep now. It really is difficult to not get enough sleep for numerous nights in a row.
