In High School, I had strained my back and got prescribed muscle relaxers. They do help, but can make you a little loopy. I shared some with a couple teammates before a game, one of them never expected to see playing time that game, he was a 3rd string RB. The 1st and 2nd string guys got injured in the 1st qtr and he played the rest of the game and he was high as hell and was incredible. He was running past, around people, he was trucking dudes, they couldn't bring him down, the coaches, sidelines, everybody were stunned. It was pretty flipping amazing, the coaches were on the sidelines talking about starting him the next week.
He got more reps in practice, the coaches were excited that maybe we had a new weapon....... He didn't start the next week, but did get subbed in early and got a lot of playing time early, but was back down to 3rd string before the end of the game. I didn't have enough muscle relaxers to spare before that game and he looked like his old self. The coaches weren't sure what to make of it and just chalked up that one good game to a fluke, the other team wasn't prepared etc. A handful of us knew the real reason, but we weren't talking.....lol
