Top tip, always carry your own supply of toilet roll :) and don't let this illness spoil your life, enjoy yourself, desstress, know that you're not alone. Replace milk with almond, soy, or rice milk. For ice cream you can buy Soy Delicious or Ben and Jerry's makes good dairy-free ice cream. For cheese, buy Chao or Daiya. Sugar free is a little hard because aspartame and other fake sweeteners make me flare. So I would use agave nectar as a replacement. Glutino brand makes good gluten free stuff.
