I go running every night, like 6 minutes into it I get a stitch and have to stop, then breath then continue then stop again when i get another one. I keep having to cut short my running even when I feel very much capable of running for another 10-20 minutes, I hate it because I come home feeling that I haven't had a nice hard exercise. I usually leave at least 2 hours after eating before I run, sometimes 3 hours. I drink about half a liter in the hour before I run. I'm 19, weigh 250 lbs and am 6'2". I've been jogging for a few weeks but am finding it hard to increase my running times due to stiches.
