Fake Nail Problem Help

Hi girls…I always have fake nails. It's like my thing this year. But I normally buy them and glue them on myself. But they normally last me 2 days before one falls off and I have to reglue then nail again and everyday from then on it's a process. How do I get my nails to last more than 2 days? What type of glue should I use? Or do you have any advice? Please help!
