I am going the 'natural' path as well. I have however discovered (for myself) that stress plays a MAJOR role in my flare-ups. If you are stressed about which meds to take and how long to take them for and the future implications of having taken them, then my suggestion to you is to do your own research.
Because i go against the grain of what my doc's expect and would want to do with me, i spend a lot of time researching things for myself.
I have had the 'york test' done and tried that with some benefit, I have used aloe with some benefit and manuka honey and the like but the one thing I know about this CD is that it is different for everyone. When I get a flare up i use the 'lofflax diet' and the flare usually only lasts a week or so. My CRP goes up to about 30 and back down to 4ish. This diet seems to be the most effective thing I have done to control flare ups.
Whether or not you go off the meds and create your own path is totally up to you and it needs to be a decision you are happy with, and knowledge will help you answer the questions. I have typed Crohn's disease and _________ with almost everything you can imagine to discover what I can. I have long suspected that their is a micro-bial imbalance/infection that is the main cause of the CD in my guts. I have been doing things like buying organic, growing what I can, getting dirty in the soil A LOT MORE to breath and soak in the good stuff that will fight the fight in the gut. type 'what's in milk' into google and see what you can see........
