I've done TMS. It had a subtle effect. One person I spoke to in a support groups said that she didn't feel anything markedly different until her first booster session after that initial round, usually recommended 6 months to a year or so after your first round. Then she said it was like a light turned on (or something like that). So, for those who had little to subtle changes in their symptoms, there is hope that your boosters may be the key. I haven't gotten any boosters yet, but I look forward to seeing if it helps.
