Hi Fiona,
I've been taking MTX for 4 years now, around the 12 week marker I found the difference in my joints. I started on a very low dose and built up slowly week by week until I reached 15mg. Try taking it at night before you go to sleep, you then sleep through the side affects. I used to find I felt sick the day I took it. It could last for hours and the sun bothered me too. A high sun factor is important. I can feel a bit tired the following day I take it, but I do not really have any problems now...... Other than the fact I hate taking it, but I know I would be in a sorry state without it, so needs must.
Hope you settle down soon.
Take care Lorna x
