No matter what I do I just cant sleep for more than 2-4 hours and am feeling exhausted. i have taken 5mg ambien for several years and it has worked for me fairly well and also take morphine for pain and xanax for anxiety.. I often wake up drenched in sweat in the early a.m. and onced something wakes me im awake for the day and any little noise wakes me,its like Im never in a deep sleep.the only thing different that ive been taking is vitamin d3.I feel like running away to someplace where theres no noise,light no interuptions just want to sleep! Is there any such place????
