Kemar, I found that I had to establish a routine, although I don't always follow it. I try to get to sleep at approximately the same time each night (actually wee hours of the AM) and I set my clock so I will not sleep into the afternoon. Since I can get a long stretch of sleep, I usually don't need naps, unless I've had a bad night. I do tend to wake up several times during the night as a result of the diuretics. Sometimes I'm just uncomfortable or not sleeping well. Try to establish a routine, eat at regular times, etc., and you may find that that helps you. If you can get some exercise, that will also help with sleep.
Kemar, my PMD suggested Melatonin, which is OTC. I found that it works to get me to sleep, but that more than 1 1/2 mg gives me odd dreams. However, I'm only 4'11," so size plays a part. Speak to your doctor about taking something for sleep.
David, I've found a reduced dose of 1 1/2 mg works for me. I'm always tired, regardless, because of the hep C and cirrhosis.
