Do you/did you have one? Did you try to tame it?

I've been fine with having *extra* milk until lately when LO began having trouble with my fast let down - lots of choking etc. Also he has been feeding VERY frequently leading me to believe he's not getting enough hindmilk. I'm trying to tame it a little right now but wondering if I will regret it later - LO is 1 month - I have a freezer stash and will be going back to work in 3 months and would like him to get breastmilk for at least 6 mos.
