I'd advise at least taking a 2 - 5 day break every so often
Even in small doses of 2 bottles a night after about three days you get mildly alcohol dependent , but the good news is that dependence will dissipate rapidly after two day or so
These are rough figures mind , you should be better able to gauge yourself , like do you find yourself worrying if there's not beer in the fridge ? Getting narky and out of sorts if there isn't , or if something comes up that will prevent you from having a beer ?
Long term , there can be scarring of the liver from persistent low doses of alcohol , and sufficient recover time should be allowed .
I was told these things , and didn't really believe them ( I'd still like the evidence presented to me in a way that allows it to be properly interrogated , as I don't particularly consider statistics to be proper science )
But on the off chance , I'd still try and take regular breaks ," Marbh é tae , agus Marbh gan é"
