Got any suggestions?

You’re two thirds through the Lemmy 3 Days No Poop Challenge.
Hang in there!
- Exactly my thought when i saw this post

Probably more effective than any of the suggestions so far:
Make sure you are well hydrated and do some exercise or at the very least a long or high-energy walk.

Depends, are you trying to poop, or doing the 3 day challenge?
- Not long ago on Lemmy this was a goal, not a problem.

This might only be me, but when I'm constipated, my go to is hydration and lettuce.
I'll get myself a nice big salad, and eat it super fast. The idea is that if you eat it fast, you won't chew as much. The partially unchewed lettuce can help irritate your guts into doing a bit of a clean cycle. (Plus, veggies are already great for constipation.)
Best of luck, and wishing a healthy one for you soon haha.
- That's a good tip. My personal choice is celery. Celery has higher water content, and more insoluble fibre than lettuce. And you can eat it pretty quickly too.

Try chewing gum, a few pieces a day.
- BE VERY CAREFUL DOING THIS!!!! you may accidentally chew too much gum, and blow a bubble so big that you float away into the sky.
  
  You could also swallow it by mistake and it gets stuck for years.
- What does it do

OP this post is a few hours old now if still nothing, you could try a single dose of milk of magnesia to get things going but continue a high fiber diet the next few days to get everything back on track.
- This reminds me. Apparently, in a pinch, you can also dissolve a few teaspoons of epsom salt (magnesium sulfate) in water and drink that. Would have never guessed that stuff is even safe to consume if I hadn't read "saline laxative for relief of occasional constipation" on the front of the bag I just bought.

The seed shells from Cassia Angustifolia
Make a cup of tea from them, wait 12 to 24 hours.
Enjoy. Just don't drink it everyday for weeks.
You can find it in herbal stores i am sure.
It is prescribed by doctors at least in some European contries

Get the flu. It'll clean you right out. The vaccine wasn't very effective this year. Ask me how I know.
- So far so good on vaccines this year for me.
- Sample size of 1 is not very conclusive.
  
  2 parents, 2 kids, one uncle, 4 grandparents all got it. All vaccinated. Not a large sample but larger than 1.

Fibers or a french breakfast : coffee + cigarette = poo (or in French CCC: clope, cafee, caca). Or if you realy need to, those gels you can put in your bum if you're into that

Second day of the holidays > can't stop pooping
Man this period isn't good for your health...

I'm having the same issue. I thought I had food poisoning because I have chills, stomach cramps, and constipation. But the only culprit would be the three cups of raw broccoli I had on NYE.
