Its just the DXM, its an aweful substance... Have you ever smelled pure DXM? Its horrible... Extracting is just plain dumb now when they have Zicam which is pure DXM now and then the Robo Caps, 15mg a cap. Extracting lemon drops is no fun at all and the sucrets method is a waste and if you ever burn the powder by drying too much you have a horrible smell in your house for days.
I use to extract back in the day, but DXM is everywhere now and its Cheap!
I actually know of people who sell weed who also sell DXM powder for like $10 a hit...
People just dont know shit about it still, after all these years of trippin, its still not a known rec drug.
The only other thing I could suggest for your puking problem, and this has helped me as well.... is plan ahead, when your going to trip, make sure that particular day you only eat clean foods and dont eat to slose to when your gonna take the DXM.
I did this once and had a great trip, only gopt a little sick to my stomach, but I didnt puke and it was a 3rd palteau trip.
Also take Imodium AD right before you take it, it will calm your stomach down and it wont be so harsh.
DXM is an awesome trip, but the getting sick part really prevents it from becoming a social drug, when your funked up on it and sick at the same time, it really is a stay at home drug.
Im baked so I may be blabbing too much...
