Switching from Tirz to Reta

I’ve been on Tirz 2 years. Lost 108lbs. Stalled on 15mg. Went off because insurance no longer cover and I’ve gained 20lbs. Time to find another solution.

Tell me all the things about switching to Reta after stalling on/maxing out on Tirz.

Did it break stall? Have you been successful?

How did you figure out dosing?

How did you find Reta to work differently than Tirz? Symptoms, side effects, pros, cons?
