Getting irritated...not giving up, but definitely annoyed. I've been stuck for about 5-6 days gaining one pound, then down a pound, then gaining a pound, and down a pound. I haven't gone over 20 carbs AND I've been working out for an hour, riding the mechanical bike and or treadmill for almost 5 miles a day now...pretty sure I'm not building muscle but I'm not losing either. However, this week I did pick up the habit of Coke Zero...I'm thinking this is my culprit, I had a bad reaction to it a few days ago and found that it has aspartame...I was so angry. I didn't mean to get them. My husband wanted Cherry Dr. Pepper from the store, well they didn't have any so I got a 12 pack box of cherry coke...didn't know it was zero. When I figured it out, I didn't want to waste it and hubby didn't want any part of it, so I checked the nutritional info...and I saw it was carb free...didn't check ingredients...has anyone else ever stalled out over coke zero??? Also, how long after cutting out sugar alcohols should it take to see a difference? I'm tired of being stuck at 238!!!
