Sounds like you've done it correctly. You're supposed to start with one capsule and add another capsule each day until you achieve at least 3 BMs a day.
I mixed up a batch of IF#1 and had some left over after filling the capsules and I store it in a glass canning jar and keep it in the pantry. All the rest of the herbs that I had left over I store them in the package they came in and put them in a sealed 5 gallon bucket. As long as the herbs are kept in a cool dark place they should be fine. If you've got enough glass canning jars its always good to store herbs in glass rather than plastic, but I've got so many different herbs its impossible for me to do that and my herbs still good.
You done good lol!
