Travel and ibs

There's a strong gut/mind connection. Anything stressful can cause reactions even delayed reactions.

I have found help for plane travel with a combination of benadryl and a hard candy infused with concentrate of marijuana.

Both seem to have a calming effect on my gut and myself as well.

I would be careful to drive while taking either as they both may make you sleepy.
On a recent plane ride I did this and was able to keep my digestive issues at bay.

This has not always been the case on International flights so I know how bad it can be.
Benadryl is over the counter so an easy one to test to see if the anti-histamine effect improves your symptoms. I would suggest a test outside of travel first to see if it helps.

Marijuana has had a bad rap for many years. Until it was made illegal in part to protect the Hearst empire from the competition being created by hemp based paper. This all lead to a propaganda campaign that was racist by today's standards.
For example "Black men will walk upon a white mans shadow."
It was in this vilification campaign that hemp was also renamed to Marijuana to rebrand it as the "devil's weed." We are still stuck with the propaganda today but I do see the tide is turning towards more states allowing it for medical or even recreational use.

Wind the time back before that and marijuana or its scientific name cannabis was often used to treat a variety of ills. I would say for me it has improved my symptoms by about 90 to 95%. I take a tincture orally at night before bed. Even if it is a placebo effect I still want the benefit. For me I work to keep my symptoms at bay more as my strategy rather than work to counter a bout in progress.

Best wishes.

Traveling with my touchy gut is always a challenge. I've been at this for 14+ years now, in the beginning before a vacation by car I did an enema 2 days prior to leaving home. The day prior to leaving I ate very, very light and the day of traveling, virtually no solids, except for a few saltine but during this phase I kept my fluid intake up. That worked for a long time. Now we don't have time (nor funds for weeklong vacations) for long car trips so that's an added benefit to the recession of 08 and then paying off school loan debt for our daughters (prior to that, college tuition). We've become home bodies and I love it. But again, I just didn't combine regular sized meals with a car trip (and if I had been traveling by plane, same regimen).

I will add that I started a new job in October with some very long work days (8, 9 hour stretches). I cannot eat lunch on these days so I've been taking one Sudafed D 12 hour pill after awakening in the morning (I start work 3 hours after I wake up, to give myself time in the bathroom). I read somewhere on these forums that the ingredients in Sudafed D are what GI docs used to prescribe for Diarrhea years ago. I thought I had nothing to lose so I've been taking these pills each day (even my days off). My gut is no longer swelled up from repeated, messy trips to the bathroom. I don't even want to put up with these symptoms on my days off, so it's become a nice way to manage my IBS like symptoms. I need to add it to my bio.
