Im sorry that your CD has come back too.
I had a resection in Sept. 07 and only had a few months relief till it grew right back - although unlike yourself, I plodded along, just kept upping the pred.
Then I had the flare from hell where even upping the pred didnt help, so although I felt the same way about the biologics as you, I knew I needed something else
I was really scared to take Humira, but then after the flare from hell I became scared not to take it.
I have just completed my second maintenance dose and I have to say I think it is working really well. I do have urgency issues, but no more pain and less frequent bm's - and that for me is a godsend
I have even dropped my pred down to 10mg which I havent been down to in years, so I am hoping this is the med that gets me pred free.
I worry what these meds are doing to my body, but uncontrolled Crohn's would be doing much worse.
Good luck with your decision and let us know what you do decide
Oh and one day I must get some tips from you on Labradors - I have a very naughty one year old golden Lab, who is too loved and spoilt by all
