Re: Have to travel on THurs which will be Day 6 - advice/
I don't know if this would work...
You could try just putting the lemon juice and maple syrup alone in a bottle and putting the bottle in the liquids bag, which you are allowed to bring on the plane. I'm not sure if they would allow you to bring fresh food on, but they might if you intend to finish it before landing. If they do, it's a simple matter to add roughly 4 tbsp and a few dashes of cayenne to a glass of water each time you need a drink. If they don't allow you to carry it on, you could at least put it in your checked luggage, so you'd have it at the end of your flight. Again, the question is whether they'd allow you to transport fresh food.
I bring my lemonaide with me to work this way, and add it to bottled water. This is even better, because you can just put the cap on and shake it.
If this method doesn't work, you could always do a
Water Fast for your travel day. A few cups of mint tea would help. I'm sure they'd have no problems with you bringing mint tea bags in your carry-on.
