I had a great response from N.O. Shotgun but some people are just different. Your body may have gotten used to the other stuff you took and if you switch without giving your body a week or so off the other stuff it can still want the other stuff and not want the Shotgun. I say if you continue to have these problems then take a week or 2 off preworkout supplements and then try the Shotgun again.
I noticed you posted this more than a month ago so let me know what you did after this posting.
