Hi! I am also starting A-L and I'm glad to hear of its success so far with your son--that's great news! I'm only a week in so i don't have much experience yet to share but i did notice it affected my vision immediately (within an hour i had pretty blurred vision).
My LLMD didn't specify storage boxes so i just keep it in the box it came in--
I have a lyme friend who follows the EMF stuff who stores her tinctures in a metal box--like a tin you would use for Christmas
cookies so maybe something like that could work well. And they are dirt cheap also!
