Hey guys,

I'm having the same problem, actually just did a search here to see what others were saying. I just recently gave up diet pop and it's pushed me back down into ketosis and I've noticed fairly moderate pain in my lower back, near the sides, and down into the pelvis. It happens every time I go into induction or near-induction and lasts a few days at least, although this time the pain is a bit more severe.

Anyone have the answers?
