Maya, each of us is here to try to optimize our treatment of Crohn's. There are many options, and no one option is going to work for everyone. Each person here has to make an informed choice about which treatment(s) is/are the best choice for them. I absolutely do respect people's treatment choices, but I want their decisions to be well-informed.
What I have observed is a lot of pressure *not* to use EEN. The OP is in fact an example of this. The OP finished 8 weeks of EEN, it worked great, and they're transitioning away from it *not* because there is some problem with it but because the doctors are telling them to. Unfortunately, the doctors have no particular basis for this recommendation.
I quote from a review article on EEN from this year
4.3. Duration of treatment
Current recommendations are that EEN is given over a period of 6-8 weeks, either orally or by a nasogastric tube . Although inflammatory markers begin to fall within the first 2 weeks of EEN they continue to improve over the 6e8-week treatment period. There is considerable variation in practice. An international survey of practice by Whitten et al. observed large variation in EEN dura- tion (<6 weeks - >12 weeks) with the most common practice to continue EEN for 6-8 weeks prior to food reintroduction [57,77].
There are no controlled trials looking at the appropriate length of treatment, current practice is based on consensus [1,5].
Meanwhile, we have data showing a rapid increase in fecal calprotectin as soon as EEN is stopped (after 60 days of EEN treatment)--despite other simultaneous treatments--as I linked previously in this thread. We have good evidence against ending EEN right there.
So what we have here in this thread is a switch from EEN to 6MP that has no actual scientific basis. It's fine if someone says, "EEN is just too hard, I want to try something else". I have no problem with that whatsoever. But I don't think people should feel pressured to switch away from something that's working.
I can tell you that I personally felt pressured not to use EEN, but it's turned out that after 6 months of continuous EEN that I would say 90% of my son's improvement since diagnosis has been due to EEN, *not* infliximab or anything else.
I support each person here looking into a variety of treatment options. While we're at it here, let's discuss some of those:
Corticosteroids: can be useful short-term, but can't be used long-term and have many side-effects; tends not to result in mucosal healing
Biologics (remicade, humira, stelara, etc.): infection risk, possible cancer risk, cost; studies show remission in up to 67% of patients; may result in mucosal healing
Immunomodulators (6MP, azathioprine, etc.): bone marrow suppression, cancer risk, various other side effects; only moderately effective--possibly not much better than placebo; does not lead to mucosal healing in a majority of patients.
Antibiotics (eg metronidazole, azithromycin, RHB-104): some promising research based on the MAP theory, but not widely used for induction or maintenance of remission. Probably underused, but research is focused on biologics. Possible side-effects include peripheral neuropathy.
Diet (eg SCD): Compliance with SCD can be very hard; no proven theory of causation makes choice of food difficult; tends not to result in mucosal healing.
Diet (EEN): no side effects; remission rates over 80% in a number of studies; can be tested independent of doctor's orders; data indicates sudden increases in fecal calprotectin after stopping; results in mucosal healing in a majority of patients; can be difficult to adhere to due to flavor (which can be worked around with tubes if desired).
Miscellaneous other treatments (eg low dose naltrexone, fecal transplants, etc.): worth investigating, but side effects and effectiveness vary widely.
These are all valid choices for different times and patients, but I think I'd start with the option most likely to result in healing that also has the fewest side-effects.
Edit: I just want to add that I know this can be a very difficult disease to get under control. Many people struggle and never find a treatment that really works for them. Some people have years and years of problems and complications. I've read about all too many sad cases, so I support whatever works to get inflammation to zero. I would hate to see someone stop using something that's really working for them without a good reason and a good alternative.
