Thanks @Joannie. Usually I can. There's always a toilet break, but the closer I get to dawn the harder it gets. I couldn't get to sleep last night because of the pain so I ended up taking a sleeping pill. I should have got up to get some paracetemol but it was cold and the sleepers were in my bedside table!
You are certainly on the horns of a dilemma. I try not to expect too much of myself but with four kids and seven people in the house the bare minimum is a large chunk of work. Hopefully I can get a handle on it. Just popped my first Krill Oil horse pill. Fingers crossed but bloody hell, the fricking expense of this bastard disease...
