Decided to sit in my mum's room. It's only 3 degrees cooler than mine, but she has the gigantinormous ceiling fan of doom in her room, compared with my 1/3 size fan in my much larger room. The breeze really helps. Also ordered a swamp cooler online which should be here tomorrow. At a minimum it will make sleeping more comfortable till we can get the A/C replaced. And afterward, it will work as the humidifier I've been needing to get anyway.
And the FK fans on my list will be amused with the fact I'm drinking LaCroix sparkling water! My brother brought a case of it home.
