Water water water. Also I will point out fiber made mine worse. I'm a power lifter so I consume a ton of protein. So increasing fiber just made the solid masses I shit larger. Not good. Turns out if you largely cut out fiber, with hifh protein, your body becomes more efficient and shits very small dense turds. That had helped me immensely. Witch hazel. Squatty Potty!!!! Have wipes at home and work.
No. If you have access to a hole to shit in that's best. I don't, in Seattle all toilets. Squatty Potty is next best thing. I am a powerlifter so I find the exercise squatting to both help and hurt. On one hand it often softens everything. On another the massive pressure of compound movements on the core contribute further to hemorrhoids, so mileage may vary from the squat for hemorrhoid approach
