Ok so, my doctor gave me some samples last week when I saw her because I was having a lot of nausea throughout the day. the first few days of using it were great, o felt so much better, I was just really tired. But now, 8 days of taking it, I am still getting very nauseous throughout the whole day. She told me to try it to see if it works first because it's pretty expensive. Has anyone else had this happen, where your symptoms came back and it seemed like your body maybe got used to it? I don't really know if it isn't working as well or if my symptoms are just getting stronger. Any ideas or suggestions?
