Sports Drink?

Tuesday's flight was much the same as Monday's. We did the same things. I wasn't quite as sharp or maybe the IP was just more demanding, but I still felt improvement. I kept angling in on final, but eventually figured out the significant undershooting winds. Only have to clean up 2 more items for the end of block. I got terrible sleep last night after drinking what I thought was a sports drink but in fact was an energy drink. Should have checked the ingredients. So I called my IP this morning and we canceled. End of block tomorrow, sim on Friday, maybe check on Saturday.
