I don't necessarily think it is the epsom salt, as I felt nauseous before I even started taking the epsom. Also, I started to feel a little better just before taking the OO (Olive-Oil) drink. Then after that it was the worst. I didn't mind the taste of the drinks, I added stevia to the epsom and it wasn't so bad. I actually liked the OO/grpfrt as I don't get to drink juice much and it tasted good. I know, I must be weird.
