My class schedule is as follows. 5:30-7 Kickboxing, 7-8:30 Judo and 8:30-10pm BJJ. During all of this I get really, really hungry which as stupid as it sounds, really affects my performance. I would eat a big meal beforehand but then I'd be all bloated and again my performance would suffer (plus chance of hurling), what/when should I eat to stop this? Thanks.
