3 day challenge: No junk food

I am a junk food addict...... i literally cant survive without eating some kind of junk food.
I have decide to challenge myself.
3 days without junk food.
1) you can not eat outside food...even salads..... prepare food at home and carry it along.
2) home prepared food should not be fried or have sugar.
Everyone knows the health benefits but we often forget eating out and eating unhealthy food is also less money efficient then eating self cooked food.
Saturday will be the cheat's day and every sunday, we could renew the challenge for the next 6 days.
I am starting this challenge tomorrow......
Anyone else interested in joining in? We could use this platform to keep each other motivated.....
