I am a bit of binge drinker. So I have drunk about 4 units of drambuie tonight and on 25th Jan I drank 2 bottles of wine and two small glasses of drambuie. Prior to that i drank a bottle of wine over 11/12th Jan and then i drank a bottle of champagne on NYE. I am hopeless should I still go ahead and have the blood test on Monday or cancel. This would be the 2n time I cancelled as I do not want fail but am struggling.
