My doses were lower so maybe not as useful, but I skipped any weaning schedule. One week I used Tirz and the next week Reta. Found what looked like an equipotent dose and switched to it. Kept the same Sunday morning schedule even though Reta's half-life is a bit longer. That was back in August and it worked fine; no going back since.
I've been taking 15 mg of Tirz for more than six months. Goal is to move completely off Tirz and stay only on Reta. Last Friday I cut Tirz straight to 7.5 mg and then took 2 mg Reta the following Monday. Plan is to hold that combination for four weeks, then drop to 5 mg Tirz with 4 mg Reta and continue stepping down. Would like to see how others have raised Reta while lowering Tirz, including their timelines, dose changes, and whether they reached Reta alone.
