Hello, Chris. Welcome to SR!
Please, please,
PLEASE get yourself to a doctor pronto.
I am currently dealing with heart palpitations...the doctor doesn't know what's wrong, so I'm wearing a monitor. Chances are pretty good that I'm having this problem now because of drinking. I may very well have this for the rest of my life...I won't know more until another month or so.
The sooner you get a medical evaluation, the sooner you can receive any needed treatment. Besides, knowing what's going on can bring peace of mind. Please be honest about your drinking history when you go.
It is wonderful that you have two weeks of sobriety. Keep reading and posting!
