Just started, PAWS question

I’ve got two days under my belt and I’m working on my third right now. I had a tiny shooter on Tuesday but I had been attempting abstinence for like a week before that. My partner told me about PAWS after I was describing some symptoms I’ve been having lately. Headache every day no matter what, tiredness, chest pain, heart palpitations. Could this be PAWS affecting me this early? It kinda sucks because I have some bad health anxiety which was a big reason why I was drinking so much. I was drinking for like 3 years every day, heavily. So yeah just curious how early PAWS can kick in, or when it started affecting yall. Because if this is PAWS I feel like it would motivate me to not drink again, since I really don’t wanna have to go through this multiple times.
