Can't help ya with the recovery, but as severe as the cramps were, it's not unexpected.
I'd be concerned about what caused such a severe cramp. If you're actually riding in upstate NY, I wouldn't expect heat dehydration this time of year. Were the efforts particularly intense? In any case, you might check your mineral consumption. Salt isn't usually a problem, so consider potassium, calcium, and magnesium. Potassium is often a problem. If you use salt, consider switching to Morton Light Salt, which contains potassium chloride in addition to sodium chloride, and start drinking V-8 (480 mg potassium per 8oz serving).
