Same happened to me. I picked up a bag of caramels locally and while in the shop, the guy behind the counter offered me a free sample. Now the caramels are 20mg per and I have had them previously. What I didn't know was that the gummy was 100mg. Suffice to say I was pretty much mummified after the 100mg kicked in. It took everything in me to muster the ability to focus long enough to get up from my desk in my office and make it to the bedroom.
