Pam - the sleeping can definitely be a sign of clinical depression and I think it is telling you pretty clearly that you should not be off your medications right now. Please talk to your doctor about increasing your dose again. I know it's expensive but the consequences of depression are more expensive.
Also - ask your doctor to check you for other physical causes - especially your thyroid. When mine is even a little off, I start passing out at 8:00 every night.
