I get blocks of 2 or 3 hours at the moment , = can we arrange a swap ?
No seriuosly the type of medication I take has a big influence on my sleeping patterns. Im not sure if 10 hours is a bad thing, might just mean thats what your body needs. I guess it depends on how you feel when you are awake.
when I was on meds that made me sleep heaps I think for me the sleeping was an escape mechanism, definately check with your doc maybe even get a second opinion from another doc.
have a happy day
