I'm starting low carb again today and wanted a protein powder. I bought what the label and reviews said was very low carb (3 grams per scoop) protein. The protein is a Whey protein (16 grams per scoop), and other protein is derived from vegetables and fruits, which I didn't realize until I received it. Well I tried it first thing this morning and it is very sweet and makes me feel like I've "messed" up before I've even started. Should I stop drinking it. I am very motivated and really want to do well. Help!
