I have store-bought falafel mix. I make the falafel by deep-frying it; unlike others, I have no problem with the balls falling apart. However, after I put the falafel in the oil, it sticks to the bottom of the pot, and I have to pry it off using a spoon. Is there anything I can do to avoid this? 
Based on your comments, there are three things you can do:  Aggressively stir the oil as soon as you put the balls in so that they don't have a chance to stick.  Use a different mix or even make your own from scratch, so that the balls aren't as dense and don't spend as much time on the bottom of the pot.  Use a nonstick pot or cast-iron pan to avoid sticking.
