Similar setup to yours, just on Reta instead. Kicked off at 2mg for four weeks, following the Lilly trial timeline. Same as you, held each amount until the scale stopped budging. Did that through 4mg and 6mg. After that I started freelancing my own dose sizing. Eventually landed at 9mg, and four weeks there got me past my second goal with room to spare. Just started a 6mg maintenance dose this past Friday. Whatever the scale tells me next decides whether I hold there or trim further. Personally I think watching the scale trend is the single best tool for figuring this stuff out. Only weigh in once weekly, Fridays, always the same scale.
