When did you start taking the full 37.5 mg pill?

Hey y’all, I’m on day 3 of taking half a pill (18.75 mg) and I’m already down 5 lbs. For those of you who started with half, when did you switch to the full 37.5 mg dose? Did you wait a certain amount of time or go by how you felt?

So far I feel good. I’ve had a little dry mouth and some extra energy, but nothing too extreme. Just curious how others made the transition to the full dose. Thanks in advance.
