I know this is an old post but just wanted to comment about this reaction to starting the pill in case others, like me, are reading old posts for advice.
I too had the extreme reaction when I went back on the pill (after being fine on it 6 years earlier). I already had bad nausea up to midday but for the first 7-8 days of the pill I had it from 5am to 6pm, so all day and so intense I had to cling onto the bed to get through the unbearable waves, plus the intense waves of fear and could only cope with milk and juice that week. I knew the pill would initially increase symptoms though, as you are adding to surges at that stage, and that once the hormones had built up to lower the surges it would get better which it did.
The nausea never returned, so if anyone has the same extreme reaction, it does change dramatically after the first week - if you can hang in! You can also take a beta blocker for the anxiety surges and a sleep inducing antihistamine like Cyclizine for the nausea surges. (Don't take Motilium or ginger as they are stimulating and make it much worse!).
