I have been doing this fast now of 29 days and I have not missed a day at work,
at first I took my lunchtime and went for short walks or stop in the chapel for prayer. but as time goes by you realise you can be around food and it doesnt bother you because your cravings go away. And you will amaze yourself to see how much self-control you have cause I have certainly amzae myself. Right now there is a box of donkin donuts right behind and everyone at work cant believe that I have not even looked.
There are times when you will make frequent trips to the bathroom but trust me its not all that bad.
