Hello, I recommend weaning off, as you would when trying to stop a medication even if not on the program. You can try setting limits so that you only take medicine a certain number of days per week, or certain doses, and slowly decrease. When I started TMS treatment, I had been taking a variety of supplements for years to help with IBS-C symptoms. Out of caution, I very slowly weaned off, which helped limit my worries.
Regarding feeling defeated, TMS healing is rarely a straight line. It is very up and down, so please know that it is common to have good days and bad, to relapse then improve, etc. Also, there are no timelines. You have as much time as you need to feel better, so try not to worry about stopping medicine by a certain date, etc.
Keep up the good work!
