That's true Oakleaf, if that hip was so stiff afterwards and that was the same side that cramped that night, there must be some kind of connection. I know my gait has changed and my distance may be just long enough now to have an impact on the (very) slightly unstable surface of the gravel trail.

Good point on the scandals, will consider that and also look at the Solray. I looked at the Nature Made Mag Citrate last night and couldn't even find what the dosage was. The other types, that are less bio-available had dose information but not the citrate so I passed.
