I'd be grateful for any advice about my problems with these two things when I play. I am not diabetic but my blood sugar level drops very quickly when I play. If I warmed up for just 15 minutes, for example, I'd be showing the first symptoms of low blood sugar by the 6th game of a singles set - the 4th if it's a hard fought one with many deuces in each game. I've also discovered that some of it might be due to the rate at which I lose electrolytes when I sweat during a game. While I have been dealing with the problem by simply eating more before I play and drinking lots of sports drinks, this isn't an ideal solution because I am getting FAT!!!
