Hi Dave,
I inject the methotrexate ( 1 ml. weekly). I used to take the oral form until my dose became large enough to make it impractical(about a year and a half ago). My rheumy also told me that the injected form works better. I haven't had any since early March though because of a surgery I had in April. I should be going back on it sometime in early July.

MTX has always upset my stomach and given me headaches, mouth sores, etc. Usually though when he raises the dose for me, my body will get used to it after a few weeks and the nausea/headaches won't be so often or bad.
I take 2 mg of folic acid daily and I also take something called Leucovorin 8-12 hours after I inject the mtx. It 's supposed to help with the bad side effects also.
I do dread Tuesday evenings though(that's when I do mine), I just can't get over that. And I'm still very careful about what I eat that day and the next.

I hope you get some relief soon. I'd give that rheumy a call back and talk to him about it.

Take care, Wanda
