the perscription says tablets in the morning, then half lytely i need to start drinking between 4-5 hours.
I've had both types, and I preferred the Fleets Phospho-soda over Go-Lytely.
After the first couple of glasses of Go-lytely, I wanted to vomit, and I still had a ton left to drink. At least with fleets, the drinking is over faster.
The prep is the laxative. It depends on your dr as to which kind of prep that they use. Some take the gallon of go-lytely (which is obviously a bad name for it), fleets phospo-soda (in the little bottle that you mix with sierra mist or juice) and others including rectal suppository. Then usually eat a clear liquid diet-depending again on your drs request. Some people can't handle the smaller amount as it is harsh, but the 1 gallon one cleans you out thoroughly, supposed to be easier but my mom strongly disagrees. It would also depend on if he is looking into a sigmoidoscopy or total colonoscopy. Best wishes to you and call the dr ahead of time to see what your prep will be.
