Owie.

Just got a B12 shot. I didn't even feel the needle, but wowwwww. Afterwards it felt like I got charlie-horsed by a bulldozer. So a word of advice, don't get the needle in your butt. Get the arm. It only lasts for about 20 minutes though. I'm running on three hrs of sleep right now and I actually feel energized! Not tired! Weeee! For any students out there like me, this might come in handy come midterm season or finals as these are used for energy and nerve preservation/regeneration. Make sure it is methylcobalamin form of B12, NOT cyanocobalamin.
