Ahhhh, my wonderful scarf is curling!!

[soakedinstars]

So I'm already like 120 rows into making my very first scarf.. I'm using the knit 1 row, purl 1 row stitching, and at first it wasn't so bad but now it's just curling like all get out. Is there any way to make it stop curling, preferably after I'm done knitting it since I REALLY don't want to restart?! :p

also, any random scarf tips to make it look nice/professional would be helpful as well.. (:
