i'd have to agree with BW - PCOS makes it all a hell of a lot more unpredictable - my ivf stim cycle, not a problem, but two of my three IUI cycles i hyperstimulated - only one lead follie, but heaps of smaller ones - and mild to moderate OHSS both times! and i was drinking 4L minimum of water every day

recovery wise - i couldn't say - but it wasn't over in a few days, that's for sure!
