Hi there,
I'm so sorry you are living with this. Sounds like you're coping pretty well, thus far, but it still sucks, I know.
NSAIDS gave me ulcers. I was taking stomach protectors and taking the meds with food and a full glass of water. Still got ulcers.
I started Remicade in July 2005 and have never looked back. When it stopped working as well, I switched to Enbrel. Like Mig and Alan, I have had very few side effects. Except I now have Alan's good looks.
Here's the thing, whether you choose to start Humira or not, you have to make this decision from a point of view of knowledge and information, rather than fear. Do your research. Look into not only the side effects, but the real life probability of them. When I started, my chances of being hit by a bus while crossing the road were greater than my chances of succumbing to one of the more frightening side effects of a biologic medication. Look into it for yourself and make your decision based on that.
That's the only way you'll make the decision that's right for you.
Hugs,
