I chose Sema after discussing it with
@Ghoul yesterday. I'm primarily after the psychological edge it might give on the addiction side, which is primarily GLP mediated. Sema is the strongest binder of that of the three, so has potentially the better effect considering my use case. I don't struggle with appetite, I struggle with just psychological urges to eat even when not hungry. So seeing as Sema seems the most beneficial, that's where I'm starting. If I see bad sides etc, i'll swap to Tirz.
It might be that it turns out just a difference on paper, but theory suggests not. Regardless, I 'needed' some GH at the same time, so it also lined up being better for cost effectiveness considering.
