Not an expert but from what I understand of the three, sema and tirz were the usual choices when it came to stopping food noise.
Hi everyone! I've been on reta for the past 3.5 months trying to deal with constant food obsession. Weight loss wasn't the goal, just quieting the noise, so I've kept it around 2-2.5 mg a week. Still bingeing and the thoughts are there though. Not sure if switching to tirz would be better. My aim is only to stop the obsessive eating thoughts, nothing about dropping weight.
