I need to take 238 gm = to what in cups
You are talking about PEG-3350 powder, brand name Miralax but available in generic brands now, too. You've been told to use it for a clean-out prep for surgery or colonoscopy, right? The label says 238 Gms is en entire 8.3 oz bottle. But if you are struggling to read the label, which specifies that a cap filled to the line marked inside is equal to the recommended daily dose for constipation (17 Gms), then you should have been given a prep kit prescribed by a doctor, or told to have the pharmacist help you. The kit has a container with the powder, flavor packets, and the same electrolytes in the Gatorade, formulated to protect you from becoming too dehydrated or depleted of minerals by the process. An overdose of this could be serious--even very dangerous if taken by a child or elderly/fragile person--and yet an under-dose will leave you not fully washed out, so your exam may be useless or be cancelled.
