Unlike most people I find fasting on days when I'm at home easier as I can keep going and making myself drinks, don't always need to be mentally focussed (and again unlike most people I don't find I'm more alert on fast days) and when I'm at work I feel so much better if I've had my morning porridge or smoothie. Fasting days are my 'low' days, unfortunately still as much in productivity as calories, so I'd rather the low productivity be at home rather than at work at the mo!
Contemplating fasting friday, too to give me a 4:3 week but may be doing a couple of hours digging so I'll see how I feel.
Have a good day, folks!
