Joski, when we were in that stage of doing cycle after cycle, there used to be a personal trainer business in the building where I work and I had to pass it on my way to the toilets (and when you're drinking 3L per day for IVF, you go to the toilet a lot). They used to have a blackboard outside their door and often had Einstein's definition of insanity written on it (doing the same thing over and over and expecting a different outcome) and after a few cycles it was a very hard thing to see day after day... BUT, we did eventually get our different outcome... and I can hear her in the next room spitting water, so I'd better run...
