I only do the gallon preps. GoLytely is discontinued from what I was told before my last scope and had to use Colyte...ugh. GoLytely is the only one without flavouring, so I'll have to check starting now for my scope in October.
What! When were you told this? That really sucks for me. How does Colyte differ? Does it have flavoring? I had GoLytely last in June 2018.
