Lack of proper sleep or poor sleep -
there has been talk of that recently - having something to do with difficulty loosing weight.
I'll go with that
I get up at 2am to make hubbys lunch and send him off to work at 3am - so my sleep is broke up because of that and I'm awake enough then that I watch TV for an hour or so before I can get back to sleep.
I'm able to get about two 4 hr sessions of sleep - but I'm not sure if I'm getting the deep REM sleep or not. I guess I am or I would be tired during the day. But maybe the REM part has nothing to do with the weight loss factor:
