I am not a guy. I did not drink when I got up in the morning. But I did drink regularly every night. My withdrawal symptoms were bad including hallucinations. I did not have heart papitations. These sound dangerous to me. If you feel your chest hurting, I think that's a good time to go to the ER. Knowing what I now know, I would go to the ER to be on the safe side. Better to go and not need to, than to not go and really need to. You will get past the withdrawals. The doctor can help you to do it safely. Take the help. It's all an investment for your future. Best wishes. Sobriety rocks!
