Diabetes is slowing me down! (a lot)

Ok, I play soccer and absolutly love every minute of it. When I am out on the feild I forget everything that is going on and just focus on the game. It is also kinda mind numbing with all the adrenaline pumping through you. But my diabetes gets in the way. I always get dizzy on the soccer field b/c of high BG and adreniline but i was recently diagnosed w/ vertigo which my doctor says could have been caused by my diabetes.  I am a fullback on my team and play the entire game every game but recently i have had to come out b/c of highs or lows or just plain feeling crummy. I want to be the best soccer player i can be but diabetes isn't letting me. Does anyone have any advice??????
