I was trying to book a follow up appointment for a refill. I have 2 to 3 weeks left, but I thought I should make an appointment now so there’s no delays. Plus I had questions on my dosage level with the next step should be. When I went in to the calendar, it showed no appointments available for May or June. Am I doing something wrong this time? Sorry if this is a dumb question.
