I do not fight with bathroom trips during the night. If you stop fighting with it, your body adapts and lets you go back to sleep after trips. They can be reduced with imodium, but in many or perhaps even most cases, it probably will not be completely eliminated.
It reminds me as well that when I signed my first lease it was a small 1 bedroom condo in downtown Fairfield right next door to the very busy Fairfield train station. Maybe less than 100 yards from the train tracks. This was back in 1995 or so. For the first two weeks I could not get to sleep because I heard the trains all night. I called my father at the time and told I was going to have to break the lease because I could not get to sleep. He said, give it time. Funny thing but shortly after that I stopped hearing the trains. Your body adapts, it like tunes them out. I lived in that condo for 5.5 years and I never heard the trains again after the first two weeks. Your body simply adjusts. Let it do that and don't fight and it will adapt over time.
