Hi I was wondering if anyone would be able to give me any answers. I'm a 19 year old girl and I'm not a big drinker but I've recently noticed that even if I only have 1 or 2 drinks I will be fine and go to sleep. I wake up a couple of hours later when an increased heart rate of around 162 and feel sick and agitated. It doesn't matter if I've ate a lot beforehand or not or even what drink it is, it always produces the same end result. Is it possible to be allergic to alcohol or have an alcohol intolerance at all?
