Tried E many times...then once my mate bought a bulb machine. For those who dont know, these machines are used to whipp cream for cakes by using nitrous oxide. Except, we sucked the nitrous while on e. OH MY GOD! keep sucking the nitrous down and ull experience ur own matrix - its like waking up in the real world...and the person pumping the bulbs into u is your own personal morpheous. Ull thank them trust me. You may not want to go any further, but go until u almost pass out. WELCOME TO THE REAL WORLD. Nitrous on E is amazing.
Just a side note: Your body is yours to do with as you please but this practice is extremely dangerous. It cuts of oxygen circulation to your head and can very easily cause permanent brain tissue damage or death.
