Hi all, I'm new with some questions. I recently had a total thyroidectomy and have started gaining weight. I started Atkins today. Along with my thyroid meds I have to take calcium 4 times a day due to low calcium. I went and bought some sugar free Tums today and didnt notice until later that they contain Aspartame. The regular ones contain sugar, so I dont know what to do. Any advice would be appreciated.
