Hello Cathy,
I have been taking methotrexate for about 13 years now and I haven't had any problems with it. The only time I did have a problem was when I tried to stop it. I had a lot of pain and inflammation then but I can't take NSAID's so I was in a bit of a mess.
Don't forget your folic acid though. This is most important. I take 5mg per week, two days after my methotrexate. Never take it on the same day as you take the methotrexate. Some dr's recommend different amounts of FA. I used to have 5mgs per day until about 3 years ago.
Don't know about B12 though, I have never taken it.
Thing is about side effects is that there are normally 3 categories - rare, very rare and very, very rare - for want of a better way of putting it. Again as with all medications, what affects one patient might not affect another. Of course if you have any adverse effects at all, tell your doctor. If you go ok with it, I wouldn't worry about what "might" happen. I do so hope it works for you.
Take care.
