For a week in advance of HalfLytely Day I was concerned about a vomiting reaction. This didn't occur partly because I put an 8 oz mug of the 24-hour prechilled "beverage" in freezer for several min.to make it extra cold. Also I held my nose during 5 gulps; didn't try to do it in fewer. Used 1 gram CrysalLight diet iced tea mix instead of an included flavor packet. (Was warned in advance that they're not palatable.)Ate lightly 2 days before the test, but still needed to drink 7 of the possible 8 glasses. Took 15 not 10 min. between drinks. Was impt. to be GENTLE w myself to prevent any barfing ! I don't have to be retested for another 7 yrs. In the interim I certainly hope a far more palatable solution can be created. Colon testing is very important -- so PLEASE MAKE THE PREP PROCESS FAR MORE USER FRIENDLY ! (Medical field should be encouraging this testing, not deterring it thru such an unpleasant drinking experience.)I wish the best to all future users.

After reading all the review on the internet is was concerned, there was no reason to worry so much. I took the tablets and about three hours later started the process, mixed the liguid and put the orange and cherry flavor packets in. I noticed the sodium taste but it wasn't that bad. Once I noted clear liquid leaving my system I did not finish the rest, left about 16 ozs. I also did not drink it quite as fast. This did not seem to have any adverse effects as my test was completed and no problems were found. Don't scare yourself reading the reviews, it really wasn't bad at all.

I was surprised that it wasn't worse, though I was thankful that I didn't have to do the kind where you have to drink a whole gallon. The Crystal Light suggestion is much appreciated (I have read that some doctors let you add powdered Gatorade). Although it doesn't turn the stuff into a delightful beverage, I didn't have any trouble getting it down, nor do I have an aversion to lemonade following. I was surprised, also, that there was no cramping. Just the urge, and the liquid coming out. However, the number of seconds between the two was in the single digits -- don't be far from the bathroom! Also, for me, the "purge" kept going on intermittently all night and right up until the procedure, which alarmed me, but the nurse assured me that it is normal and expected, and that they have suction machines and all for the liquid during the procedure. Sorry to be gross, but I was relieved to find that out so I thought I'd pass that on. Another unexpected thing -- drinking that much cold liquid so quickly makes you cold! I was shivering and needed to bundle up. It's never going to be pleasant, but I feared it would be much worse.

Although it worked for me as far as prepping me for a colonoscopy, I dreaded drinking the large amount of the solution. My anus burned every time I eliminated the watery discharge. With technology today, there has to be a better way to prep one's bowels for a colonoscopy.

Getting ready for uterine cancer surgery. Nurse said to put crystal light in the mixture, worked great. No adverse effects.. drank it evry 15 minutes rather than 10 and didn't get the upset stomach.. Also kept busy, walked around rather than just sitting.

Horrible salty taste - gives a bloated feeling from drinking so fast - its worse to drink it slow because the taste is so aweful.

I became violently ill - throwing up causing much pain - sweats and difficulty breathing. After taking the pills I vomited harshly and then tried to continue with the drink - after 2/3's done I throw up with much pain and fright. I would not use this product or recommend it.

This medicine is downright disgusting to use, and far worse than the previous treatment five years ago. The taste is revolting, and the amount of fluid required to be consumed makes the stomach bloated and uncomfortable. There has to be something better and more friendly to the patient than this stuff. It's like sending yourself to a torture chamber where you waterboard yourself on both ends. Perhaps if physicians who order the medicine for their patients tried it themselves it wouldn't be proscribed again. Again, awful stuff.
