Were you more worried before getting the shot, Wigobi?

I am interested in Wigobi, but now that I am actually about to start, I have a lot of worries about this and that.

I am curious about the effects, but I keep hesitating because I am worried about side effects or whether it will affect my daily life.

For those who have actually used it, what was your biggest concern before you started? I am also curious to know what turned out differently than you expected once you actually tried it.
