I think it is. It has somethign to do with sleeping on a flat mattress. Inevitably, I sleep on my back. Can't help it, even though I am not supposed to do that. Soemthing about cutting off the blood supply to the baby. Anyway, Sleeping on a firm mattress gives me the worst backache.

Usually, I go downstairs and sleep on the couch. No aches from that, hehe, but it is a bit too short for me (it's a love seat). It's funny to stretch out!

I've had back problems like that from sleeping on a mattress that was too firm, too. Also sometimes my pillow can affect it.
