The tolerance pattern with GLP-1s is different from the adaptation that happens with most medications - the cravings returning usually means the dose isn't suppressing the signal fully anymore, not that the mechanism has failed. Most people find staying at or near the effective dose longer rather than cycling delivers better sustained suppression than any other approach. The dose titration ceiling is real, but you generally don't hit it until you've worked through the full available range and given each level 8-12 weeks.
