Thanks everybody!
Well, I ended up with what I think was a migraine yesterday! I had a headache that started at the top of my head and went right down my face and I was so sick. I was lying down in the dark and can vaguely remember OH coming in and massaging my forehead and offering me drinks. I suddenly became very aware when he said I wouldn't be able to go to collect puppy Duggie, so I took loads of painkillers, got a good sleep and now feel the way I normally do (grumbly achey gall bladder and a bit bleugh), so I feel great compared to last night!
I think it must have been stress and lack of sleep catching up on me.
I've got Duggie's downstairs crate all ready, I've put some of Gari's favourite toys in it as a welcome present from his big brother. We go to collect him when OH comes in from work, so leaving about 3pm, I think. I'm getting very excited, but OH wasn't this morning, as he is still too sad. I think it's maybe because he doesn't talk to anyone about Gari much, and when he does it's to say he wishes he was here. Whereas, I talk about him all the time and remember all the funny/cute/silly little things he did. I know he will love little Duggie when he is here though, but he will spend most of the time worrying about him.
I'm off out now to stock up on batteries for the camera!
