if I can hear the tv I can't sleep. it keeps me my sympathetic nervous system active (fight or flight).

But I do love my white noise machine on the 'rainstorm' setting. it help me shift into parasympathetic system (rest and digest) for a deeper more restorative sleep.

MS is a constant 'attack' on the nervous system so every little bit helps...
my dogs snore is so relaxing, unlike my hubbys that drives me nuts!!
