Yes, it stinks.

Have you considered some of the fatigue meds such as Provigil, Ritalin, Amantadine, to name a few?

Also, make sure you do not have a hidden urinary tract infection, which is common in MS and can make you feel very run down but not experience the usual pain upon pee-ing.

And, have you had your B12 level checked lately? MS people have a higher than usual incidence of B12 problems which causes severe fatigue.

i.e. don't assume its your MS: Go see your PCP. Could also be thyroid.
