I Have Had Dizziness, Lightheadedness And Brain Fog For The

I have had dizziness, lightheadedness and brain fog for the last 3 weeks. 3 weeks ago I had a long weekend of drinking. I am now fully hydrated. Went to the doctor, most bloodwork was fine. Also got 2 different cardiograms and a Holter test. Revealing my heart is in great shape. The only blood issue was a AST SGOT of 52. Could a high liver function ( probably from the alcohol) be causing dizziness and lightheaded still after 3 weeks?
