Funny you posted this. I've been considering the same swap for a couple of weeks. I tried adding Cagri on top of Reta and it handled the hunger that Reta leaves behind for some of us. I began at .25 mg Cagri and moved up to .5 mg weekly. I'm currently on 3.5 mg Reta and it works well. The reason I'm thinking about Tirz is that I believe I had less inflammation on it before. Maybe that's just in my head.
I've used Reta for almost a year and a half. It worked well early on, but now at around 9 mg weekly the results aren't as strong. Tirz seems better for controlling hunger signals according to what I've heard, so I'm thinking about changing over. Some people mention good results from pairing Reta with Cagri for better appetite control. Has anyone tried moving from Reta to Tirz or adding Cagri?
