How long do you let perfumes macerate for?

Hi, so I really like gourmand perfumes and decided to get Eclaire by Lattafa because SO MANY people on this sub seem to love it for how it smells like vanilla, caramel, sweet milk/cream and I just had to try it lol.

But oh my god, it smells like the complete opposite of that. It has an overwhelmingly sickly sweet alcohol smell. It's like if I mixed lots of sugar with isopropyl alcohol. I hate it so much but I don't wanna give up on it yet. Apparently, the first sprays can smell bad or chemically, but tell me when will the sprays start smelling good??
