Hey David,
First, sorry to hear you have been diagnosed. Even though you knew you might have it, because family members have it, it still sucks when you are diagnosed...
In recent years it has become pretty standard in the US to go for biologics (remicade or Humira) immediately for anyone who is newly diagnosed and isn't virtually symptom free. Back in the old days (let's say pre-2005) the steps were first immunosuppressives (aza/6mp) and then biologics (back then only remicade existed). Even before then doctors would go for 5-Asa first and aza / 6mp later on (biologics didn't exist 15 years ago...).
Imodium doesn't really treat the problem (inflammation), just the consequence. So that isn't really an option for Crohn's patients.
What you should think about when deciding for or against the standard drugs is a. what symptoms do you have and are they in any way severe and reoccurring (if you are in deep remission without any problems, then there is no need to take drugs) and b. if you have symptoms and they aren't going anywhere, do you want to take the risk of the effects of constant inflammation (scaring and potentially strictures that might even need surgery).
What I have learned in my 14 years of living with Crohn's is that priority number one is getting to a symptom free deep remission way of life. And at least for me (and for the vast majority of other Crohn's patients in remission) this only works if a lot of pieces of the puzzle come together - diet, sport, treating any vitamin and other deficiencies, stress relief, etc. and of course also long-term medication in the right dosage.
Hope these thoughts help a bit. I would encourage you to read a lot of threads on here to get an overview over Crohn's and what people do and don't do about it etc. Information is key when it comes to managing Crohn's effectively.
Cheers,
A
