Overcoming MS Diet experiences?

I was diagnosed last November and my husband (our chef) has been amazing; embracing the OMS diet - even following it himself. However, after 6 months of without falling off, it’s been hard to keep to - so cheese and a very small piece of meat are things I allow myself twice a month. (Would love a credible cheese alternative in UK!?!?) We know we’ll never know if following OMS has ‘made a difference’ but wondered if others have made Dietary changes - and their experiences?
