nutrozol

I have been using nutrozol in the morning And have been getting sleepy during the day. Is it because I should be using it closer to bedtime or is it because it's giving my body an energy boost and then I'm crashing after. I do feel really good on it though

so I have a problem with my sleeping. I don’t have an issuegoing to sleep but what happens is I wake up early like 2 or 3 to pee and thencan’t go back to sleeping do you think nutrozol can be used at that time to help mefall back to sleep or should I still use it before bed
