I haven't been as stringent on my use of the products lately as we have been out camping and it seems it's more difficult to stick to the plan but I can definetly feel the difference when I'm not using the products. I don't have as much energy during the day and especially towards the evening I start to get drowsy earlier than I realized I did when I was taking the products on a regular basis. So I'm going to work at getting back in the habit! I feel so much better when I continue to take the products on a regular basis.
