cb,
IMHO, your best options are #1, and #5.
I would recommend:
1) slippery elm powder
2) l-glutamine
3) rectal meds
4) diet modification
5) LDN
If you are interested, there are things IMO that you can control, which will have a direct impact on
your disease, the symptoms you experience and their severity.
I was able to control my UC into remission through various
supplements, probiotics, diet modification, and LDN , low dose
naltrexone.
For more info on the protocol which has put me into remission,
please go to this link: https://www.healingwell.com/community/default.aspx?f=38&m=1666318 , and look at the 11th post.
I hope you feel better and let us know how we can help
you.
