Traveling, scary situations!

Hi , travelling to Norway sounds amazing, but I completely understand how you're feeling! Travel and anything out of the ordinary gives me so much anxiety, too.

For me, eating only very safe foods the day before traveling helps a lot. Since the anxiety usually gives me a flare in the morning anyway, I like to get up a lot earlier to deal with that at home, and then take some Imodium or other medication if I feel like I need it.
I always pack very safe, very plain snacks too, because I tend to get hungry at some point and I don't want to risk anything.
Are you traveling there with your partner? If yes, I'd talk to him about what might happen if you're flaring, like needing lots of bathroom breaks, not being able to talk when you're unwell, and so on. I personally can't be social during a flare and prefer listening to calming music and focusing on my breathing.
In addition, I would also make sure that his family members are aware of your condition and that you might not be feeling well at first because of the stress, just to manage expectations. This way, you won't have to worry about making a bad impression if you can't participate in meals (which has happened to me so many times).
I'm also going to link 2 articles about travel here: https://irritablebowelsyndrome.net/living/traveling-ibs-expect-best-plan-worst, https://irritablebowelsyndrome.net/living/how-to-travel-with-ibs. I really hope this helps.
Hopefully, everything will go well and you'll have an amazing time!

Great advice by Karina. I dont travel much so I dont have advice but I will be going to a wedding 2 hrs away and staying for the night at a hotel and already planning on that 24hr period away from home and 4hrs traveling in the car.

Safe foods day before and day of
Light snacks
Immodium that morning even if I feel fine, maybe day before, not sure yet
I'll bring Tylenol with me
Water, Gatorade
Lycopodium (for bloating)
Roll on castor oil for belly at night

If I hadnt had a flare in over a week before I leave I may take Hyoscyamine day before and day off instead of Immodium.

Imodium seems to work well blocking things up but Hyoscyamine slows things down and takes care of the cramps.

Good luck and have fun in Norway.. Think positive and know everything is gonna be ok!
