For Bowel Preparation "Used for colonoscopy prep since it was the smallest amount to drink over the longest time. Tasted like Sprite. Drank 7 8 oz. glasses of water over the next hour. 90 minutes and had 3 explosions. Then 2 more glasses of water until the 2nd dose 5 hrs later. 2 glasses of water, 30 minutes later, awful stomach cramps, dizziness, numb fingers and toes, dry mouth. Thought I was going to pass out from the pain. Worse than labor pains! Took 30 minutes to pass. Went to bed exhausted. Definitely cleaned me out!"

For Bowel Preparation "Much more expensive than the Miralax prep. I paid ~$80 out of pocket. I did like the fact that you only drink 10 ounces (split in 2 doses). Then you follow up with clear liquids of your choice. The orange flavor was tolerable. I was instructed to take the 2nd dose at 8 pm. I woke up at 3 pm with almost unbearable stomach cramps. I've had a baby and kidney stones, and the pain rated right up there! This was my 4th colon prep, and I have never had this experience before. I got a thorough cleansing, but I don't know if that sort of pain is worth having this prep."

For Bowel Preparation "It worked, but it caused me to pass out. I took this as instructed - 1 dose at 4 pm and another at 8 pm. My doctor's instructions were to drink 2 16 oz glasses of water/beverage or more after the 4 pm dose, and that liquids could continue to be consumed after the second dose until midnight. I drank some herbal tea. Things went fine after the first dose, and it seemed gentle enough. I went to the restroom several times and things seemed to be moving along. I took the second dose and by 10 pm thought I was done. I woke up at 12:30 am with stomach cramps and a pounding headache. I had watery diarrhea and became very dizzy. I stood up and passed out, hitting my head."

For Bowel Preparation "I am doing the Prepopik for the first time. I've done the Golytely and the Miralax/Gatorade preps in the past. The Prepopik is tolerable. It's only 5 oz 2x, so it's not too difficult. I started feeling it work within the first half hour of taking the first dose. My stool was clear a couple of hours later. I took my 2nd dose 6 hours later as directed. It felt like I was pooping fire. It was HORRIBLE, take your breath away burning. I did remain clear yellow, though. The biggest struggle for me was drinking the at least 24 oz after the second dose. I couldn't take in any more liquid. My stomach was a mess. I had mild cramping, tons of gurgling, and a very uncomfortable digestion feeling. This prep wasn't worse than any of the others."

For Bowel Preparation "I was given this as prep for a colonoscopy. I had read negative reviews, but tried it. If you hold your breath and drink down the 5 oz., it's not bad. It gets warm as you mix it and would have been better cold. It started working about 50 min. after I took it. I noticed that warm/hot beverages (black coffee or tea) made it work faster. I had no stomach cramps, etc. with this. After the 10 pm dose, I thought my last trip to the bathroom was around midnight, but it was at 1 am. My doctor said I did a great job with the prep, so I'm sure it worked. I suggest you have a 'light' breakfast in the morning - don't eat like you'll be starving for days. I think a heavier breakfast is what keeps people from clearing out quickly. I'll use it again!"

For Bowel Preparation "Today I started my prep at 4 pm as instructed. I then drank a container of broth, 32 ounces, ginger ale, and water. Way more than the cups I was prescribed. All this caused was nausea and stomach cramps. Not one BM. Second dose at 8 pm. Already up to 40 ounces of fluids. I feel bloated. Nothing else. I haven't eaten in 24 hours. Thankfully, it was a sample."
