Is the jump from .50 to 1MG quite noticeable in symptoms?

My doctor has suggested that I go from .50 to .75 dose (I’m using a 4MG pen) and am on week 6 of .50, but I am concerned about how I’d use the residual dose in each pen without wasting any since it’s quite expensive.

My question is for folks who have made the jump from .5 to 1MG since this is technically double the dose, did you notice a dramatic increase in symptoms? Is it worth going from .50 to .75 to bridge that gap for several weeks? How did you use the residual medication in the pen with a .75 dose?
