I get terrible red-eye, a spliff to myself and my eye's go extremely red. I don't even have to be that stoned. But i use Eye Brightener eye drops which sort me out. if i put them in, people just think i'm a bit tired rather than stoned (apparently my face goes a bit "droopy" when stoned.) Some red-eye will be because smoke getting in, but you can tell when you get smoke in your eyes because it's quite irritable in my experiences.

as for drymouth, i only get it if i think about it. if someone mentions it, i'll get it, but if not, i don't. I dont think it's dehydration really because that implies all you're body to be dehydrated. For me, i want a drink just to wet my mouth again, not to rehydrate. There's definately a difference between "i want a drink cz im really dehydrated and not had a drink in a while" and "i want a drink because i got dry mouth"

i hope that all made sense, it didn't make much sense to me and i wrote it and i'm not even stoned, what's with that? lol
