Is there anything I need to prepare before getting Botox?

I’ve scheduled my first Botox consultation, but now that the date is approaching, I have so many questions lol.

I heard that Botox is a relatively simple procedure, but are there still any precautions I should take before the treatment? I'm confused because I see conflicting information online; some say to avoid alcohol for a few days, while others advise controlling my exercise.

I usually take supplements as well, and I was wondering if I should mention that in advance. Since it's my first time, I'm worried about even the smallest details, haha.

When reading Botox reviews, I saw many comments saying that the procedure itself was over really quickly. I actually saw some people saying the consultation took longer :)

Still, since it's my first time, I want to go in the best possible condition. I think I would be upset if I went ahead without knowing what I was getting and the result was disappointing.

Please let me know if there was anything you prepared before getting Botox!! I'm also curious about any tips that would be good to know in advance ^^
