Sudden weight drop--normal?

The stall-then-drop pattern is almost universal once you have been on it long enough to notice it a few times. The bounce after the drop is frustrating because it looks like you regained, but it is just the equilibrium resetting. Trend direction over 2-3 weeks is the only number worth caring about.
 
The thirst increase on reta compared to Mounjaro is pretty consistent - the glucagon pathway has a real effect on fluid dynamics and more water intake can show up as extra scale drops. A sudden 5 lb drop after a steady pace is usually water, hormonal, or a delayed response to accumulated deficit rather than anything alarming. What dose are you running and how long have you been on it?
