I dont know about the nicorette. I did the patch and hcg at the same time and still lost. I take generic synthroid and have both times I did this diet. It wont effect, it will actually help. Hypo-thyroid can slow down weightloss. And HCG actually promotes a more healthy thyroid too. Which in turn will promote more lbs to drop.
I am on day 7 of vlcd and have lost 12.5 lbs.
