The mood change side effect on sema is underreported relative to the GI ones, but it's a recognized pattern - the GLP-1 receptor presence in the brain means some people get appetite suppression and some people get mood dysregulation, and it's not always predictable in advance. Stopping because of psychiatric effects is entirely warranted, and the stomach pain situation is also worth a thorough prescriber review - both together suggest sema's receptor footprint in your system is producing effects beyond the therapeutic target. Tirz uses a different receptor weighting and some people who don't tolerate sema do fine on it.
