Hi there, you might try a little "reverse psychology" on yourself. Try bending the second string down or away as you bend the third string up! This may give your body enough of the message it needs. If you end up actually bending the second string down when you try this, make it less of a bend until it just stays put. This should help....

Good luck, this is a classic riff that is well worth the time and effort and once you get you'll have it for life!!!
