Two squares off the full bar gave me that body vibration/electricity feeling that is common with Mushrooms. I couldn't imagine what consuming even half the full bar would do, let alone consuming the full bar. I not only highly recommend the chocolate bar but also highly recommend Devine being the one to order it from. Easy ordering process, quick shipping and the most impactful customer service aspect for me was they responded to my inquiries seeking additional information. That stood out most from my overall experience with Devine and I will be sticking with them to quench my Choc Mushroom cravings until given a reason not to.
