laminate over uneven chipboard due to flooring joists.

[Surfingpastie]

I have chipboard flooring through my lounge and dining room but for some reason the floor has a slight slope going from the lounge into the dining room. It's enough to make funiture across it tilt. I want to lay long plank laminate but can anyone suggest how I stop it from possibly lifting at the joins over this slope or causing the laminate to become bouncy.

I laid a laminate floor in my kitchen 2 years ago, acoss the width of 3.5 mts. it ran off by 20mm added to which it was a mixture of wood and concrete and had meeting lumps and bumps all over. I phoned the flooring importer who advised me to take out the kitchen units, have the floor skimed.
What I ended up doing was using the thick green underlay it was a bit bouncy for a couple of months but that stopped, it looks ok.

My wife who drove me mad for the laminate in the first place, has now decided she no longer likes it and wants tiles. Don't you just love em to death.
