Yeah I was looking for a sub better suited for tips that make things you shouldn't do easier, but it wasn't unethical or illegal. I generally just use this if I'm on a train without a drink and feel a headache coming on or some other situation where I don't have a drink and can't get one before a headache starts, as when the headache gets bad enough, pills don't help much.

But yes, you're right, it affects absorption and if you're not careful it can get stuck in your throat etc. Just figured there are people out there already dry swallowing, might as well give them a tip to make it easier and at least lessen the negative impact a bit.
