i am between a grade 3 and a grade 4 spondylolisthesis. i got "lucky" and got the progressive spondylolisthesis after an accident at age 12. long story.

i'll keep in mind and bring up the insomnia factor to my dr. he is wonderful about responding by email.

my insomnia is more from pain. i can't be in the same position for too long. if my ab and back muscles relax...i get slippage. the nerves being hit wake me up like being jabbed with a knife. then it takes me awhile to relax again and fall back asleep. usually around the time to get the monkeys up.
