will, kedushah is right - the best, most effective way of not having a mikrah laylah is to practice shmiras einayim and not have hirhurim issurim(also, if you sleep on your stomach, you're almost 100% for sure going to have one, on your back too is assur) - but the other aitzos certainly help.
Just to clarify, it is only possible to control what position you are in when you're
going to sleep (which is supposed to be on your side). Once you're asleep, however, this is not in your control, so don't worry about it.
