Hey girl...
Aww, you poor thing, really feel for you. It's so typical huh? We try and help ourselves, and then something beyond our control tries to stand in our way!!
You should still be feeling positive though hun... As you know, flare ups can come at any time, and it's very possible it's the anxiety of starting LL, and not the shakes themselves which have effected you this way... You will feel the benefits as the lbs drop off, and could ultimately have a huge positive effect on your symptoms... so you should still keep smiling!
In answer to your question, no, actually I had already come off the mesalazine, and the steroids, and all the other things I was on, months before I had even thought of going on LLT. However, this was not due to being in remission, but more to do with being fed up of taking so many meds... with many of them prescribed just to offset the side effects of the others... It got to a point where I didn't know what was helping and what was hindering, and was feeling more and more bogged (pardon the pun!! lol) down with it all.
So I just quit all meds and decided to give my poor body a break.
Surprisingly, even that seemed to help a bit. But I still suffered when eating certain foods, was still anaemic, and often had no energy and felt generally low...
Oh, and I don't blame you for refusing the steroids... I only took them when was really bad, but hated the side effects... and yes, was always hungry on them! I also tried the infliximab drip, which did nothing except cause me to have drug induced lupus! And that's a whole other story! I tell you, I've tried it all over the years, and it can really get you down huh? x
As for mesalazine effecting ketosis, I think you'll be fine. Because of the way it works, it should have no effect on being in ketosis, I'm pretty sure of it.
Aww, thank you... Yup, am over the moon with hitting goal, and to have no colitis symptoms either, well... I can't remember the last time I was so slim, or pain free!

But it will happen to you too hun... I'm no special case, and so just stick it out... You're showing real determination, strength of character, and intelligence by the way you're tackling it... and those things to me say 'success story'!
Good luck, and get posting another 6 times, so you can PM! Lol...
