Hey Erin, how's your fatigue, any better? Definitely not getting at least seven to eight uninterrupted hours of sleep each night is going to add to your ms fatigue and it is cumulative so your symptoms will get worse if you are not sleeping. As contrary as it sounds, a half a zoplicone, (7.5/2) usually does it, and doesn't cause that hangover effect. A few days of effective nights sleep and you may start to feel better. That is if you are not already taking something.

One bad night of sleep for me costs me about three days minimum to recover in fatigue, cog fog and including numbness.

As I wrote to Woodhaven, in her Ritilin thread I just started this drug for fatigue and at a low dose, so far it is the most effective for me to date. Not only is giving me energy without hyperness, but is lifting my cog fog. It does not work like this for everyone however, and is a potent stimulant.
Take care, I hope you are feeling better this weekend.
Sandra
