When I hit a plateau I tend to review my materials to get a fresh perspective and see if I've fallen in a rut or absentmindely slacked on portion control. Also if you keep your food journal you can look back and see when you were losing and see what meals/foods you were having at that time and use those plans again.
Added some more exercise may give you a boost too. I know you said you hate exercise but an easy way to do more is to go for walks at lunch and after supper and to take stairs at work, you apartment, the mall instead of the elevator. Get off the bus a stop or two before your regular stop and walk the extra blocks.
Walking is free and every little bit counts!
