My understanding is to take it "with " the meal - meaning just before, during or immediately at the end of your meal. I have done all three and things are going well. Tonight I was clearing the table when I remembered. I wouldn't bother with it if I've remembered a couple hours after.
I like to put the day's pills in the little blue holder so I have them right at the table. If I'm going to be away I put them in my purse so I have them when I eat out.
If you are keeping a journal, that would be something to note.
Good Luck to you.
