I started on Tirz in Oct, down 85lbs and hit a stall at 15mg that I've been stuck at for 2 months. Reading through the forum I saw Randy’s “ghetto” Reta stack and decided to give that a try. Going to add 2mg of Maz to see if I can break through it. Will try Reta, if all else fails but have been super happy with the Tirz.
