Yo bro…sorry to hear about the cramping. I’ve never suffered from that before…what I have had is what I’d call a massive spike ‘come down’ just before a final due to too much caffeine/sugar drinks. Lethargic feeling,constant urinating and yawning. Try coffee as your source of caffeine and maybe some Guarana just before the race as a quick pick me up. Ive found that a supplement like PowerDrive is great for rounds as the come down is gradual.
