Getting of track?! After doing so well!

For the past 25 days I've been right on track! Lost 7.3 kilo grams!! Started out at 78, with a goal weight of 64, and now look! I'm at 70.7! I'm so close, just another month and I'll be there! But lately I've been cheating around a little :'( !! Not that I've exceeded my calorie limit,,, never have i done that, but i just am not eating as well! I used to eat 700-900 calories a day now i eat 1300 in comfort :( I'm also getting lazy and not doing my 30-60 minutes of cardio!! So my question is.. What keeps u going?! I don't want to mess up after making it this far!! What r ur tips to keep going, Most of u have been on here for 4 months and have lost 30-50 pounds, and you're so determined like i was and I want that back!! So what are your tips? What pushes u not to give in to bad cravings?! Also please not - I'm Vegan :))
Thanks in advance guys! <3 Love ya'll <3
