Protein Drink/Nausea?

Hi all. I am doing a modified version of the Time Out. All is going well, in fact down 10 pounds since Friday Morning. I have having a bit of a problem though. I have never really done protein drinks, it was not something my doctor suggested (before the revision). Well now I am giving them a go. Problem is I have been very nauseaus this weekend. It seems to get worse after I have a protein drink. What do you suppose it is? Could it be not getting enough water? Saturday is when it all started and I really pushed the water that day. Had in 60 oz before noon. But it did ot seem to help. Any ideas?  Thanks, Bridget

Wow Bridget please be careful and call your doctor if you don't feel better today. I would seriously get your electrolites checked if you can. Nausea is a sign of messed up levels. Also, I dump on certain protien shakes like the Atkins ones in the cansThey just don't agree with me.  Please keep us up to date and be careful!
