I agree, if it's a large portion of your income then maybe time to cut back, but there are ways to be cheaper. For example, I had a bad habit of having a meal out almost every day. Even just cutting it down to 3-4x a month rather than 3-4x a week has a huge effect and I don't feel deprived - in fact I feel healthier and so does my bank account! ;)
If you have to have the energy drinks, getting them in bulk from Costco etc. can also trim down your expenses.
Like others have said, MMM isn't about depriving yourself of everything. But, if you have $10k debt, earn $4k a month and spend $500 on eating out, then there might be a problem...
