Finally biting the bullet, hey?
First up, I would say that you need to be really, really ready for this. The first few nights are going to rough.
Second, you might find it's easiest to stop the feeding by getting your DH to settle him in the night. or else finding some other way to settle him - ie, cuddles might seem too much like a prelude to bf to start with. Eg, I had to jump from bf-to-sleep to standing up & singing before returning to lying down together.

The advantage of doing it at this age is that he is old enough that you might be able to strike some sort of deal with him in regards to feeding - ie, extra during the day and none at night or something like that.

I've posted about this before, but we night-weaned DS at 14 months. He was so very angry and screamed his head off at first. DH went to him all night the first couple of nights, then needed a break, so I took over half way through the night for the next few nights and just held out as long as I could before feeding him, until eventually he was falling asleep from sheer exhaustion then having his feed at wakeup time. It took probably 2 weeks before he stopped asking for it altogether. He hasn't stopped waking up, btw

Good luck!
