Your fasting sugar is in the impaired range but not in diabetic range. We can confirm your diabetes
status by doing a hba1c. If it is above 6.5 you are a diabetic. If it is 5.7 to 6.5 you are a prediabetic.
The symptoms you have point towards more of an alcohol withdrawal
effect rather than diabetes or heart problem. However we would not ignore your chest pain
and I would you get a full cardiac profile including tmt , echocardiography
and ecg done .
