i had to take this a few weeks past, and i would not reccomend taking it after your meal sorry to say, i had to take mine before 8am the morning before i went in the next day, plus a second sachet late afternoon, plus you are restricted, to what you can eat, i could not eat any thing after 2pm but was allowed a clear soup for supper, if you look on the instructions which came with these powders in explains it to you, the only other thing you could do if you really dont want to miss out, is see if they can fit you in another time.
