Stop taking caffeine/alcohol because you'll develop new allergies to supplements/foods/beverages such as teas that will give you odd reactions. You may be more prone to panic attacks due to those reactions (they can involve racing heart, etc.).
The reactions won't necessarily be hypoglycemic but you can suddenly feel awful pain, inflammation, bags under eyes, etc. That's what I get after a bit of buckwheat. I used to eat a lot of it with caffeine.
