Haha you guys are so funny.. Okay here are some tips I have to start it off: (It may have spelling errors or have too much info, so if we actually want to post this somewhere, someone will have to edit it :o )
1) Make sure you bring a cushion and it's best to have a cushion that was created for problems like AF's. An example of this is the Donut Cushion - which basically has a hole in the centre. Using this cushion can reduce the pressure on your fissure so when you're sitting, it doesn't really feel like you're sitting (Note: this particular cushion may not help everyone completely, but it may be very helpful to some).
2) Be SURE to take all of your regular supplements/softeners with you. This includes - all stool softeners or laxatives you may use, metemucil/benefibre/whatever you use to get your fibre intake, your multivitamins/vitamin C, anything else that helps you have smooth BM's (e.g. flax seed oil, aloe vera, prune juice, etc.). If you are going for a short trip, you can put the desired amount into smaller cartons that are easy for travel - but keep in mind - it's always better to have more of this stuff than not enough! ***Be sure to bring whatever medicine you use (e.g. diltiazem, nitroglycerin, etc.)***
3) Bring a few packages of baby wipes and keep them in your purse/handbag (make sure you keep a purse/handbag if you already don't). For emergency bathroom breaks or if you have to use a public restroom, the toilet paper can often be REALLY hard. Just bring your flushable wipes and use them throughout the trip. **ALSO BRING Q-TIPS if you use this to apply your medication***
4) Bring some hand sanitizer/soap incase you ever need to apply medicine with your fingers and can't get it off! Hand sanitzer/hand wipes are really useful for travelling especially when you need to eat.
5) DO NOT EAT ANYTHING THAT YOU WOULDN'T EAT AT HOME! You need to be just as careful on the road as you would be at home (if not MORE careful)! This includes: pizza, cheese, milk, etc., and whatever else normally causes you constipation or irritation towards your fissure. Be extra careful about what you eat, and aim for more salads and healthy options.
6) When travelling on the road, there are often farms or markets where you can stop to pick up fresh fruit. Carry fresh/clean water with you, so that you can wash whatever fruit you buy. EAT FRUIT! This is an excellent way to keep up your fibre and ensure a healthy BM - just pick up loads of fruit on the way (e.g. grapes if that doesn't irritate you, peaches, plums, and whatever else you find helps you). Picking up fresh fruits & veggies can really help you stay healthy.
7) When you're eating at Buffets or Restaurants (sp?), always check if they offer fruit platters. For Restaurants, try to pick healthy options like vegetable stir-fries/less meat and alcohol, etc.

Keep your bum clean. Try to bathe/soak in the tub if you get the chance.
9) If you can take pure aloe vera juice or gel, it may help you to apply this incase you irritate your fissure and need some calming.
10) RELAX! I've always found that I have less pain during a BM when I am totally relaxed or when my mind is focussing on something apart from the BM itself. Relax, enjoy, and have fun - as long as you take care of yourself as regular, you'll be fine :)
