Cramps after training?

I get these pretty frequently after I train legs. I drink tons of water and take muscle relaxers, Valium and stretch and it seems to happen pretty frequently that I get woken up by severe cramping in my inner thighs. It's so bad I literally have tears in my eyes and beg for help. Anyone have any insight or also experience this?? It's only after leg day.

I always cramp on leg day, even hamstrings.

I always cramp on chest days.. Like a mother fucker !!

Hurts like a mother fkr to cramp on inner thighs . Its
due to lack of magnesium supplement combined with dehydration due
more to creatine. Read in a mens health to drink
pickel juice due to high magnesium for quick relief . Also some good NAC powder tossed in the post workout shake is also a great prevention .
