I'm terrified of fasting. I really like food.
I'm completely embarrassed to say that I've tried to fast before and have failed. I know you aren't suppose to go bragging about fasting, but if I don't tell someone, I'll talk myself out of it. Easily. I'll find an excuse or convince myself it wasn't God's idea, it was a misunderstanding...yeah.
This article made me feel better (although I'm starting with 1 day...not 40).
Another helpful key is to fast when you're completely out of food. I've put off shopping for a while out of laziness but it is now a blessing. Nothing to tempt me. Even if I talked myself out of this, I would have to drive somewhere to eat anything (therefore giving me an opportunity to talk myself out of talking myself out).
I have lots to pray about today. It's been a hard month.
