I'm scheduled for a colonoscopy tomorrow. Hard to believe it's been 10 years since the last but truly believe I should go through this since developing a fissure late last year.
I'm doing the clean out today meaning nothing to eat since midnight. Also using the doctor recommended cleaner, Prepoooptik. Really vile, nasty stuff. 
Strange to me that the prescribed method for Prepotik is one dose at 5:00 p.m. followed with 5 glasses of water over the next 5 hours. Then repeat starting 5 hours later at 10:00 p.m. Good gosh, if I did that I'd be pooping all night.
My brother, a surgeon who also does colonoscopies, told me I could just as well take the first dose at noon, the second at 5:00 p.m. and hopefully get some regular sleep. Hence, I'm doing that - well sort of. 
I couldn't start until 2:00 p.m. today as they all wanted to eat out at the Olive Garden for Father's Day after church. I told them in no uncertain terms that I was not going to sit there and watch them eat while I nursed a glass of water. I did relent and take them all to Wendy's where I could sip a coffee as they gorged themselves - on my dollar!
The Prepoptik does work - sort of like gastric munitions. The detonations are hard to predict so I'm staying close by the restroom. Although my fissure has continued to heal, I suspect I'm going to be sore by the time this is over.

Now66, colonoscopies are not fun that is for sure, also if you have a healing fissure this can make it a bit sore so you seem to know what to do and are prepare for what will come next.
Perhaps during the colonoscopy the doctor can take a look at the fissure and see how is doing.
It took a year after my last colonoscopy  to have the doctor do an internal exam after I developed a fissure because the area was so bad I could not let nobody near it.
So I hope everything works well for you, you are lucky to have a surgeon as a brother.:D
I Wish you the best.

Wish you ALL THE VERY BEST !  Yeah i know that feeling when normal food is prohibited.

Hi NOW66,
Just wanted to wish you a minimal pain experience and the best of healing! Good Luck!

Good luck tomorrow!
I recently had a colonoscopy and I asked the nurse to use TONS of lube during the procedure, and she did. I wasn't sore at all afterwards!

Good luck for today!

Finished the colonoscopy early today with an excellent report. Doc says my fissure is healed but have a few minor hemorrhoids. (Actually I'm told we all have hemorrhoids. The problem is enlarged hemorrhoids.)
The preparation was another issue and I would like to warn any of you who need this.
I took the last packet of Prepoptik at 7:00 p.m. followed with 4 full glasses of water by 9:00 p.m. I really didn't have a great deal of activity after that and thought I was essentially done when I went to bed at 10:30 p.m.

Wellllllllll, come around 11:30 p.m. I awoke to violent rumblings, dashed for the bathroom, and made it - only through the door before the nuclear detonation. Oh my gaaaaaawd. 
Apparently I caught the door but missed the light switch as next thing I remember I was laying on the bathroom tile, in the total dark, in the muck, with my wife calling through the bathroom door.
Seemed like it took forever before I could sit up on the stool while my long suffering wife cleaned up the floor. (I'm gonna owe for this.) It was even longer before I could stand up long enough for a shower.
Once cleaned up and back to bed, I slept fine though the wife swears my thinking was none too good.
Once in for the colonoscopy, I related this to the nurses thinking I had a terrible reaction to the Prepoptik. To me they seemed a bit cavalier about the whole thing and simply said I'd gotten dehydrated which upset my electrolyte balance.Well whoo hooo. Wish they'd been laying in that crap.
The doc appeared to be a bit more concerned and ask if I'd hit anything on the way down - as though I'd have known.
Looks to me like they should have warned me about this possibility. Also believe I'll forgo the Prepoptik - if there's a next time.
Also believe I'll start in the morning and camp out IN THE BATHROOM should I do this again.

Please go-away: Surgeon brother, who does anal repairs and colonoscopies, lives in Fond du Lac, WI.
Same brother, who is scheduled for a colonoscopy next month, says he has a lifetime supply of Fleet’s phosphasoda prep which he intends to use. He claims it is more gentle but taken off the market because it destroyed kidneys in a few people.
I used the pill method for clean out 10 years ago but that has been banned for the same reason. Too bad. It was violent but manageable.

Ahh..  poo  poo lucky you. Take care and keep that humor rolling..just luv it.
