If you are (or think you are) a heavy drinker or alcoholic, then it would be advisable to get your Vitamin B1 tested regularly to keep an eye on your level of Thiamin as alcohol destroys this much needed (but little known) vitamin. You will prolly have to pay to get it tested 'cos it's not available on the NHS unless you're an in-patient, but it'll be worth it so that your medical team can catch it early if your levels drop below the reference range.
