I have been drinking fairly heavily for 5 days. before this nothing for 6 weeks. how long should i wait before i have a ggt blood test.

Be brave! EZ duz it: If you are being monitored for compliance with an abstinence program, the real question is how you will stop. Your drinking endangers yourself & probably other people. Once you start, stopping is very hard. If you have a sponsor, tell them you've had a slip & want help. You're smart enough to have found healthtap & your life & health are far more valuable than a lab. Wait a week on the test.
