Welcome aboard the forum it's nice to have you with us. Pull up a cushion, or a chair if sitting on the floor isn't your thing, and make yourself at home.
A rather nasty job that isn't it. Little bits of food waste from dinner plates is also a major villain for bunging up sinks. I've got a little filter insert that fits over the plug hole in the kitchen sink and it's amazing how much muck it traps and prevents from clogging the waste pipe.
