Hi Angel,
Try to hang in there. It takes 2 months for mtx to take effect. I remembergoing off it in my first attempt at taking it. I felt so ill on it and everyone said I looked grey, then after afew months break I started it again at a lower dose and slowly built up to my full dose of 20mg per week. Now I adore this med.
I have very little swelling compared to what I was like before and if I go off it to fight infections I swell up terribly so it has had a huge impact on me.
Plus I can now tolerate it, have very few side effects. A bit of a headache the day I take it. Try to dring large amounts of water to help your body cope on the day you take the tablets, see if that helps at all. Or ask your rheumy about lowering the dose and rebuilding slowly back to where they want you to be.
Hopefully you'll feel the effects soon.
best wishes, golitho
