teething and sleep

My boy is getting four molars plus I think he might also be getting his incisors at the top and this has been going on the 6weeks now. Yes it is definately teeth as they are all just starting to pop through. He is just a baby that cries from the minute they start moving.
My question is what do you do to add your teething babies sleep?
I was feeding him when he was just getting one tooth at a time but now that its six teeth at once he'll suckle for a little then cry so I'm not feeding him anymore as I don't need to be drained by BFing all night as well as not getting any sleep if its not going to work.
I give him pamol or nurfen but I don't like to do this over such a length of time even if I am only giving it to him at night.
I have welda teething powder and calmmed which is good but he's still waking and it usually take me a good hour or more to settle him.
He will full asleep but you can see him chomping away even in his sleep.
When I hold him he will cry with pain still but as soon as the pain stops he snuggles into me and keeps chewing on his hands.
Sorry for the long post I just feel so bad for my little boy. He gets teeth so slowly and they cause him SO much greif.

Thanks will try the ice and am using everything else.

We were up for four hours last night just crying and chomping on his hands. THis morning the tip of the next tooth is through.

Get the room really warm and toasty. It may help
