For the past few months I have woke up and about 30 seconds after waking I will shake all over my body. (More like vibrating), for about a minute. Then immediately get hot and sweat for about five minutes. Then goes away. I,m taking medicine. (Sucralfate, Naproxen, xanax, ambian, percocet. But only Sucralfate and Naproxen the past few months.
