This is so weirda and I dont know if its a coincidence or not...any feedback?

Ive been stuck/stalled at 140 for 2 months, but have been continuing to follow OWL. I had great weight loss in induction and so have been fairly confident that Ill break through this stall eventually.

However, it seems like I have veen bouncing the past two weeks at 139, 138, 137, etc. But every other day or so Im back at 140. What is strange is that whenever I go seem to go below 140 I feel achey, weak and have gotten leg cramps. Either my body prefers 140 or maybe those days I havent gotten enough water/potassium (?) and so Im holding on to the water (thereby going back to 140)?

Just wondering if the bouncing or feeling funny with a breakthrough rings a bell with anyone. Ive been thinking its pretty odd.
