Question About Heart Tightening

Hello,

I don't know who to ask about this besides a doctor. But about a year ago I attended a friends birthday party. I had a few drinks and started to notice my buzz wasn't just a buzz. It felt as if something was roofed in the drink(s.) i looked up the side effects of what I was feeling and the only thing that i felt that was related was Speed. I feel fine in general but every once in a while i will feel as if my nose is clogged. I feel like my chest is tight at times. As if my heart rate is slow and sometimes normal. i don't know if it's Heart Arrhythmia or what. And sometimes I will feel a slight tingling/numbness in my face, arms and hands. I can breath normal through both mouth and nose. but like i said before, sometimes my nose feels clogged. I rarely get these symptoms. And I usually get them when driving or sometimes at night. I also stopped drinking caffeinated drinks because I felt the tightness again. Any questions, theories, etc would be great!
