So I received a sample pack of the G8 and I had to try it last night. And my honest opinion is the taste of it was not very tastefull to me. I had to chug it down. Now I may have used too much? I used the entire sample pack with 16oz water. Now as far as being able to sleep. This product will help you sleep. I normally do not get a full nights rest. Well I slept so good last night I over slept by and hour. And was not fully awake until now. Which is 8 am Texas time. I took this product abouy 9:30pm last night.
