I was very sick on the mtx day too. It helps when I take it at night and sleep over it. As for the stomach pain issue, have you tried to take with food? One is not advisable to take it empty stomach. I am okay with it until now though I still very sick on the day of mtx.
It sounds like it is more likely caused by the Celebrex. Celebrex is a strong NSAID/anti inflammatory and they often cause gastrointestinal or stomach ulcers. Are you taking them after you eat? If not put something in your stomach firsts.
Talk to your doctor. Prilosec helps to prevent the stomach upset & controls the acid erosion that Celebrex can cause.
