I got all the way up to 12.5mg of Tirz and weight loss slowed down for a few months. Decided to micro dose Reta at 1mg. Every month I have increased Reta by 1mg and decrease Tirz.
Currently I pin 7.5mg of Tirz on Saturdays and pin 4mg of Reta on Tuesdays. Surprisingly hunger suppression seems to have increased for me even after lowering Tirz.
