Hydration we discuss a lot, and this might be part of an earlier thread...we'll see if Hotfoot needs to straighten me out on this.
Here is the symptom: the neck. Does it get stiff, and a little crunchy (when it's rotated around a bit)?
This was happening to me, and I'd thought I was drinking enough (might have been), but looks like I need more electrolytes/minerals.
Has this happened to anyone else?
