They did not work for me.
I can only speak from my experience but when I took it it had no affect. In fact I fell asleep 30 minutes later. I do not drink coffee and generally if I am worried about falling asleep behind the steering wheel or when I have work to do on the computer that will require long hours I simply take a standard, cheap caffeine pill with 200mg of caffeine. In most cases it works well except with regular use it causes me to break out. I am over 50 and don't need pimples. I bought this for the same purpose and hoped for the same results; being wide awake with my normal wits and senses. These pills did not work for me so I can not recommend them.
