I also started crossfit 4 months prior and continue 5x week, and I also cut out drinking everything except water. I aim (and usually hit target) of 100oz of water a day. I've lost 7lbs, NOT due to cool sculpting... due to committed healthy clean eating and diet. But I believe cool sculpting helped my problem area. I did the procedure 2x, the second time about 1 month after first.
I do credit 70% of my outcome to diet and exercise, and wouldn't expect as great results if using the procedure by itself. But if you can truly commit to working out hard, cutting sugar and processed foods - cool sculpting can assist your goal.
