that is my best advice too go back protein shakes if you have to. Or you can also try the eat protein first use fillers ( calorie free popsicles, and pickles are my trick to trick the head hunger).Good luck it is really hard for all of us to break old habits.
I have certainly wasted alot of money on shakes.My best advice is to get a decent unflavored and add your flavor to taste with fruit,cappacino, juice, crystal light. I love desinger whey avail at Vitamin Shoppe. Lots of flavors if u like that or a decent size double the size of unjury for 22.99.
Vinegar works, Found some in my car too. I just filled them to the top with vinegar let them sit for a day or two then washed them out with soap and water. Smell gone.
