Here I am... OHSS queen at your service. I missed this thread because it was the day of my EPU.

What Chez has said is correct. OHSS is painful and utterly awful. I've had it twice, the first time I battled on at home with my abdomen full of 5L of fluid and in agony. The second time, I couldn't stand the thought of going through it at home (and DH put his foot down) and I ended up spending a week in hospital and a month off work. And I wasn't quite as sick as the first time! Both times my clinic took me to EPU, but there was no transfer as I was just too sick. All embryos went to the freezer.

If you are concerned about being on a dose that is too high, speak up! At the very least, insist that they monitor you closely. My dosage of puregon is generally reduced after each blood test just to try to keep levels under control. We managed it this time, and I'm in line for a fresh transfer.

When it comes to things that you can do to avoid getting it - LOTS of water. 2-3L per day and a high protein diet. It's best if you can stick with low-carb and low-GI as well (particularly if you have PCOS). I saw during this last cycle that when I stuck to the low-carb, low-GI, high-protein thing, my levels were very well controlled. I had one big jump which scared the clinic, and also coincided with the day that I didn't watch what I ate quite so closely.

In short, OHSS is hell, but it's not the end of the world. Take care, and keep in close contact with your clinic if you are worried.
