Leg and foot feel numb now

Last night was my first time actually drinking, and I got pretty drunk but not black out drunk. I woke up this morning and my whole left leg feels mostly numb. My leg limps a bit when I walk now. When I was laying down I tried flexing my leg and got a charlie horse type cramp in my calf. Even having my foot flat on the ground with no shoes on, I can’t manage to wiggle my toes. I can only curl them inwards.

Google gave me results of peripheral neuropathy, but it says that’s mostly for people who drink more often and longer term. This was just one time for me, I don’t plan on drinking continuously. I don’t have any other symptoms and no hangover. Will this go away?? (I hope so) I’m 21 if age matters
