Changes showed up for me in roughly a day. At first it was more about how much I could comfortably eat than losing the drive, but that drive faded later too. It feels good to treat eating as fuel instead of the main event. Food thoughts disappeared eventually though I forget the exact timing. Ten months in now and I have to watch calories and protein closely or I end up under 1200 a day without realizing.
How did the opening week go for people starting tirz, especially the 2.5 mg amount? Did appetite drop sharply or was the change minor at that level? Any side effects? I began at 2.5 and now struggle to finish plates, with zero food thoughts or snacking urges and no noticeable downsides. Wondering if that lines up with others. Does the body adjust so doses need raising later? If this holds I see no reason to move higher since it suits me fine.
