can it last days or weeks or years? whats the maximum?
Depends what you're talking about - however big the dose you peak at 3-6 hours after dropping. That's all the fun part of the trip pretty much over. Then it's just the annoying after effects waiting till you can go for some sleep. A bigger dose isn't going to make the fun part last any longer.
The brain only has so many receptors - you don't go on increasing the trip with dose.
For the normal dosage range I would agree but things get different when you overdose.
