Is there anything I should know before a Botox consultation?

Lately, I feel like my habit of grimacing is visible whenever I take photos, so I'm looking into ways to manage it. Since I tend to frown unconsciously even in everyday life, slight marks remain even when I'm just standing still. There's a limit to how much I can cover them up with makeup, so I'm thinking about getting a Botox consultation. However, now that I'm actually trying to book an appointment, I don't know what questions to ask. I'm curious if the amount of treatment varies by area, if I can return to my daily life immediately, and how long it takes to see results. Since this is my first time, I don't want drastic changes; I just want my wrinkles to look natural and less visible. For those of you who have received Botox, was there anything specific you made sure to check during the consultation? I'm also curious about any discomfort you experienced after the procedure or the aspects that turned out better than expected. I would appreciate any advice from those with experience with Botox.
