Lactaid and drinking water

I am so glad I found your comments regarding Lactaid. Although I haven't experienced the vomiting most of you have mentioned, I have suffered the last few weeks or so with diarrhea and nausea. I found drinking water has kept the thoughts of vomiting at bay. However,I have gone to bed in the fetal position spoken about and slept. When I began Lactaid, I purchased the "best" brand. It was working very well. After the first bottle, I bought one of the generic brands. Now, I realize the mistake I have made. At first I thought they weren't mixing well with the "hotflash" medication I take, but after elimination testing, that isn't the case. Reading your blogs have just verified my pain and my need to either go back to the "best" brand, or stop taking Lactaid altogether. Thank you and have a painless day!
