Advice on sudden alcohol symptom

So I am 29 and I’ve been fine with alcohol for about 11/12 years, just recently the last 2 times I’ve had a drink, I’ve felt warm, a slightly elevated heart rate still under 100bpm however and a stuffy nose, find it extremely strange, I don’t feel sick or anything the part I find weird is the stuffy nose, first time was with Jack Daniels this time was with white rum and it’s only been 1 or 2 drinks, I lost a lot of weight 36kg in total and I don’t know if that’s had anything to do with that
