i've only taken xyrem for 2 days so far, but i've slept worse on it. i'm taking 4.5 ml. i sleep on most sleep meds, i just get a hangover from them. so i was hoping xyrem would allow me to sleep without a hangover, but i'm not sleeping well on it period. is this something that will get better on xyrem? i know it's a potent dose b/c i definitely feel intoxicated from it.
