Welcome! Patricia made some good points, and it's true docs (mainly in Europe) have seen a liquid diet induce remission, but the problem is, patients tend to fail to maintain remission once they stop using the liquid diet.
It's interesting that you found out milk bothers you, but not cheese. Maybe it's because cheese has less lactose. If you are already interested in gluten-free, soy-free, milk-free diets, then you might want to check out the Specific Carbohydrate Diet (SCD), which my daughter is on (she's 23) and which has helped many Crohn's patients. More info about it can be found here www.breakingtheviciouscycle.info
Not allowed on diet: milk, soy, grains, canned vegies, sugar, most canned juices, processed meats (like hot dogs, ham, or other deli meats), processed cheeses like Velveeta.
But these are OK: most oils, butter (but no butter or anything else with "natural flavors" because this phrase could mean almost anything has been added), aged cheese, homemade yogurt, fresh or frozen fruit and vegies, honey, nuts, some juices (like Tropicana OJ and apple cider), poultry, meat, eggs, game (like buffalo meat), and even some forms alcohol (for instance, dry, not sweet, wine).
The best way to start is to first read the book, "Breaking the Vicious Cycle," to make sure you really understand the diet. Before jumping into the diet, it's best to start the first few days on the introductory version, discussed in the book and on the website. The website has a great Legal/Illegal foods list which you can quickly refer to in order to make sure a food is OK.
It's great you are seeing a new doc right at the start of the new year! It would also be great if the new doc checked your iron, B12, and folic acid levels. You might want to start getting copies of lab reports and keep them in your personal files. Even docs don't always interpret lab results correctly - for instance, a lab can say B12 of under 300 is normal - true, but this doesn't mean healthy - if you have a level of below 300, you are probably deficient and need a shot to quickly up your levels. Also, most Crohn's patients have low vitamin D - without even having your vitamin D tested, it probably makes sense to take about 600IU of Vitamin D3 daily. Too much folic acid in a supplement is not safe so first, your folic acid level should be checked.
