i used the maximum strength robo (actually the equaline shit from osco, 4 bucks for 2 bottles) but yeah I over did my dosage earlier and I fuckin tripped so bad I wanted to cry, and fuckin though my heart was failing even though it wasn't it was just my mind playing tricks on me, man I was so fucked up earlier, but yeah make sure that what ever ur taking has nothing but dxm in it, make sure your in a damn good mood when u do it, and if at all possible have someone there with you in case u freak out. with that being said, have fun, and happy trippin
