Cagrilintide

Hello! I plan on starting cagri tomorrow for the food noise and need some advice. I’ve come on here a couple of times regarding cagri but I’m a spazz lol and scared. I will do a VERY low dose most likely 250 micrograms or less. Just out of curiosity how soon does it kick in? Is there anything I can expect as soon as the first couple of hours? I’ve heard it can take anywhere from hours or weeks. It’s hard to find resources online regarding this so I would love to hear about anyone experience!
