Newbie with a question re:oversupply

tweedle29

My milk came in 1 week ago, and since then, I have been constantly engorged and in pain. I saw a lactation consultant, and per her advice, I am only nursing on one side per feeding. I hand express just a little on the other side if I need just a bit of relief. I have been doing this for 5 days, and while it seems to be a bit better, I haven't noticed a huge improvement.  I am also leaking a ton (have to wear 2 breast pads so I don't get soaked). Does any have any experience with this and an offer advice? How long do I do this for before the issue resolves?
