ok what EVER you do, dont get BAKED lol. ive done dxm 4, maybe 5 times now, all but the last time were without weed, i wiegh about the same as you too. Now last time i did dxm i did 600mg, which ive done a couple times of before(ive done alot more than 600mg) so anyway i had a bowl, skulled back the 200ml's of tussin, had another bowl, then had ANOTHER bowl, and i think maybe another one im not sure, anyway i smoked a fair bit of weed. I pretty much just ko'd and woke up with the come down, waste of 20 bux on my part. i dont really fall asleep from getting stoned anymore but with dxm i just basically collapsed lol, so yeah DONT get absolutly stoned like i did just do a bowl, no more.
