I started methotrexate 3 months ago on 7.5mg weekly. I have had no sickness but just found the first two days I was so wiped out I couldn't even lift my hand to get the TV remote! But that was a one-off.
It started working after a few weeks and it did wonders for me. My previous multi-site joint pains went completely (I started my diagnosis last year unable to move from joint problems).
It has, however, reduced my white cell count down to minimum levels, so I may have to give it up if they get worse, but I've had no illness, and that's being around my three year old as well!
So whilst I was petrified to start it, it's been a god send in my life. Just a pain in the arse when you have to have a blood test every month, as I like to be out of the country a lot. So I spend a lot of money flying back in for a 20 second blood test! Cheaper than having the blood tests privately abroad, though!)
So purely from my point of view I'd recommend it.
