I've noticed my stomach starts to hurt a little bit JUST BEFORE the actual trip sets in, when I feel that naseua or pain I just think "Give it a few more minutes!" lol. I don't like the deslym, I've never tried it but I hear the extended release is bullshit. I'd hate to wait 4 hours for a trip. May have my info wrong though.
the first time i did it my stomach felt a bit nausea right before i started reaching plateau but when the peak kicked in i felt fine then and athe rest of the trip, i even felt great on the come down. i smoked a couple bowls of good weed it calmed my stomach right down, also tryin some zofran, they have generics too, it makes the nausea go away, i like to eat a vicodin when i do the dxm cuz it interacts with the trip
