It makes no difference for the come up or the intensity if you use oral or sublingual. LSD has a really high bioavailability and there's supposed to be something about it's kinetics that doesn't make it work faster with different kinds of administration. IM and IV is supposed to only have slightly faster come up too, and same intensity as oral.
Purportedly dropping liquid LSD in the eye is supposed to increase the come up slightly too, but it's a really stupid thing to do and the intensity is the same again.
Personally I've found that LSD sometimes can have an ideosyncratic prolonged come up time - for no reason really.
Anyway, just swallow it, because it makes no difference.
