The only way I've learned how to get rid of the fever is to indulge myself with music (5sos, cover of 5sos songs, and songs that 5 sos covered) also you can try listening to bands they like (nirvana, green day, blink 182, etc.) You can also try by setting a picture of them as your wallpaper, or put a picture of them in your wallet! It not that hard!!
