Is that just the old menopause thing (I've been doing that for 10 years) or is MS contributing?
The old menopause thing does interfer with sleep, that's for sure. And, I seem to recall a study earlier this year that identified disturbed sleep patterns in people with MS. So, I think it could be either one.
As Melody said, there are also lots of medications that can interfer with sleep. Progesterone is supposed to help sleep. Quoting from John R. Lee's book, What Your Doctor May Not Tell You About Menopause
, p. 107
Many of my patients have volunteered that the first benefit they perceived from using natural progesterone was an improved sleep pattern. After years of unsettled sleep they now look forward to retiring each night...
So far I'm happy to say I can sleep just fine. But then again, I'm also taking progesterone. Just maybe it's helping the sleep and the MS.
