I have had a request from my ex to do a hair strand test to prove my alcohol consumption is not excessive. But what is deemed as excessive In family court? I started drinking again at Xmas after 6 Months off after we broke up. I have probably drunk on average 8 Pints once a week since then, never before or in the care of my son. There has been an occasion with my family where I drunk 3 times about 8pints a day in a row. I am worried it will show in a hair strand test I have drunk to excess and my son will be refused contact with me.
