Last year i had some hormonal depletion problem, due to which I got depression and migraine and also suffered from high heart rate and weird sensation inside head for months. Now I'm back to normal, but whenever I drink little alcohol(like one mug of beer), i dont get sleep at night though i feel dizzy, whenever i close my eyes i feel like something is racing inside my brain and it doesn't allows me to get sleep. I had drink by 2pm,whole day i was fine, but only during sleep at night I feel that some war is going on inside my head. Sometimes i get up feeling thirsty, after drinking water i feel like something is flowing down from my head to the entire body and my heart starts racing faster, also i see problems like i have to forcefully take deep breaths. Please let me know which doctor shall i consult for this.
