I'm a 27yr old male 5'8 150lbs. I started playing tennis regularly (taking lessons) in january and now am playing 3-5hrs a week. Recently (the past two weeks) i've been experiencing symptons consistent with hypoglycemia / panic attacks / anxiety / increased heart rate / dizziness while on court. I feel faint but never actually faint. I usually can continue to play. My coach says I need to get in better shape/ eat better. I'd like any suggestions anyone could give me as far as a specific dietery regiment or nutrional supplements i should buy or any other advice i could so that i continue playing without these attacks. thanks! i really need to fix this!
