tricks for setting bangs in the morning?

so I have sideswept bangs but my hair is slightly curly so they always curl upwards and look really bad unless I'm having a really good hair day...
In the morning I usually wet my bangs (when I wake up they're all messy) take a round brush and get it under my bangs, turn from under so they curl downwards rather than upwards and blow dry them at the same time. they usually look good for about 2 hours then they somehow curl upwards again throughout the day and I can't really take my blowdryer to school.....
so what are some tips so that they don't curl upwards throughout the day? should I change how I do my routine? thanks!
