Hi Cookie Monster,
I think you can lose your weight if you quit Coke / Mochas....
Anyways, if you are addicted to mochas and coke... it is quite hard to ask you to stop everything completely. Usually if you are addicted to something, it is the best to cut the portion a bit by a bit... both for body adjustment and also fulfill your needs at the same time.
I will suggest the following which you can try... first.. you need to tell yourself that you can only get either Mochas or Coke for today... Remember just to start it slow... let say you take Mochas, prepare 1 cup Mochas.. but pour into a smaller portion and have a glass of water beside.... now.. whenever you feel you want to drink.. take a zip of Mochas and then drink the water after... this way you can slowly decrease the cravings of Mochas or even quit it as well. Same as Coke.. get Zero Coke instead of regular.. limit yourself to drink 1 can of coke maximum... one zip at a time if you want to drink and then drink water after that zip... if you can do it consistently.. you will be getting there to get rid of it!
Hope this helps and let me know your thought!
Cheers...
