If you are serious about this, you need to clear your schedule for a few days.. You need to look at the big picture and make this your main focus.. I adapt an attitude such as this " there is nothing work backsliding", good luck
Hey Jan, congratulations on day 3, you most certainly should not take anything as it will undo the last 3 days !!!
Many people do work while going through detox and pull through.
It may not feel like the ideal situation at the moment, but it beats sitting at home clock watching and over-analyzing everything.
If you can get yourself moving around now while so early in recovery, you will train your brain to keep doing this and you will have a much easier time mentally.
Take care and hold on : )
