The alcohol reduction on Tirz follows the same reward-circuit mechanism as food noise reduction - the GLP-1 and GIP receptor components both touch the dopamine pathway that drives seeking behavior. For people who were regular drinkers before, the shift tends to be more pronounced than the appetite change because alcohol had a stronger reward signal. Twenty pounds alongside that behavioral shift is the combination that changes the actual risk profile, not just the appearance. The 'old self' framing usually refers to the version before both habits took hold, which means the current trajectory is exceeding that reference point.
