Thank you Colleen for the info. My husband will be starting his third full round of TMS. He did not receive booster treatments which I believe is the reason we have to keep starting over. We have to continually fight with insurance to get treatment and by the time he gets approved he has fallen back so far that he needs a full round. We will not let this happen again. We will fight for the boosters well before they are needed and hopefully this will help.
