Answer:
If taken too much you could potentially feel a "high" from it, but that's because it can make you tired.
So it would be like talking a sleeping pill and trying to stay away. Other than that, no. It treats motion sickness.
If anything you might get constipated or actually vomit or have diareah if taken too much or too frequently. Also the possibility of vertigo(which again can feel like your high, but it's your brain on tilt mode.)
Now it you have asthma or glaucoma or an enlarged prostate,
it could cause serious problems.
So I highly recommend not trying to get a buzz of of it.
You're not going to get anything with it, but sick.
