Hi doctor, whenever I take alcohol, say even a single peg, my heart starts pounding, my body gets hot, and my eyes become blood red. I m 30 years old now. I immediately consulted a doctor and he said nothing to worry and he found that I have high diabetes , and gave medication for that.now it is under control but even now if I take 1 single peg I get all the above mentioned symptoms. Please advice. Thanks.
