Doesn't sound silly to me. If you like DMT and it lasts longer for you, have you tried acid too? Can be much milder than DMT, but much longer trips. Personally when I smoke DMT (well, changa) it lasts 5-15min so I enjoy it as an experience, but doesn't let me really do any interesting thinking like LSD does. That said, I've only tried DMT a few times (haven't "broken through" yet), but do have a couple of grams waiting for me when I can get somewhere to pick it up...
