Can you survive with RM50 for a week?

Yes, it's my new determination. I don't want to draw my saving and don't want to use my ATM card too. The challenge will start next week, only RM50 a whole week of 5 days of my working days. I live about 4 km from workplace and need gas too.My gas will be RM30, then the balance only RM20. My plan is to fasting on Monday, Tuesday and Wednesday. There will be no more goodies buying for my kids. I will cook for the meal (the groceries still left for a week meal). I had been fasting for most of my weekdays recently and I can see a huge difference. I feel not tend to buy junk food and unnecessary stuff. Here's some comment and like to post here for my own motivation. Most is a funny comments: ~I had tried to survive with RM100 per week. Life suck. ~This is one of the way that you can survive. 1. Breakfast - oat meal. (RM1. or less) 2. Lunch - Any meal around RM 4. 3. Dinner - eat salad, or boil potato with baked Bean or Tuna (RM 2) a day = RM 7/- * 7 RM
