i had puregon, which is virtually the same as gonal-f - just made by a different company - have had 6 cycles in 12 months, and the last one, i was exactly like you are now! i got to day 4 of injections and ended up getting sent home from work cos i felt so sick. they rearranged leave so i could be off for the rest of the cycle! on the upside, it only lasted til EPU - afterwards i was still sore from the EPU itself, but the nausea and everything settled right down. i had EPU after 9 days of injections then trigger... i also found it wasn't all day - it would come and go every few hours, i'd sleep for fifteen minutes, then come good for a while...

hope you feel better soon- good luck!
