Hi Lee,
Yes, the “block and replace” medication is quite established now, I’ve been on it for 18 months now and am coming off this month – this is where the fun starts!
The theory is that there are less adjustments to make to your doses than trying to lower your metabolism, and if you stay on the medication for about a year there’s about a 70% chance of being in remission and staying that way.
It’s seems to have worked for me (fingers crossed!) – hope it’s successful for you too.
