I remembered posting on this topic, so I thought, what the hell, I'll try vinegar and baking soda together. So, I used a 8oz. bulb syringe to administer it. I had two plastic cups. One with some baking soda mixed with water and vinegar mixed with water. I think they were 16 oz cups. I don't know how much vinegar and baking soda was in each. I just dumped a little in there, like between an 1/8 and 1/4 cup of each. Then I diluted both with warm water. Probally a lower concentration would do the job.
First I injected the baking soda solution, then the vinegar. The first time I did it, I held it for 10 sec or so, then expelled, but it seemed like I could not hold it as long with the second and third time I did it. The later ones I expelled immediately.
You get a Pretty forceful expulsion, but not too bad. It was neat because you could feel it reacting in your intestate. Very neat feeling. Also, when I expelled, it felt like soda coming out of your ass. Similar feeling to soda on your tough I would say.
It really got the fecal matter out too. As you would expect, a very gassy expulsion too due to the CO2.
Pointers-
Bath tub might be good due to really short, if any retention.
Inject the baking soda first. I tried the vinegar first, it burned really bad and I could not hold it.
If not in your tub, do it really close to your toilet. I laid on my bathroom floor and did it.
Inject the vinegar fast so it does not have time to react. It seemed like if I injected it slowly, I would have to rush to expell.
I think a rinse or two might be a good idea after. I rinsed once.
My butt does not hurt now, so I don't think I did any damage. I think it worked well because there was not a very high volume of liquid. I never could get a full syringe, so there was less then 16 oz in my but. Pint, right? 1/2 a quart.
As always, be careful and have some fun! 😃
