Hi there
Well, I'm still brand new at this so I am no authority but...
...I guess that changing behaviour is hard enough - changing one's genome...now there is a challenge!!!
Seems to me that moving from alcohol to coffee is a massive leap forward - is there any chance that you could substitute something for the coffee, at least from say lunchtime, that moves you forward another square? If you can't solve the issue, maybe whittle a bit off it?
Only day 16 for me so I have a lot of questions but not many answers at this stage, I'm afraid! :-)
Best of luck with it though!!!
