we can't give a dose; seeds are far too random and variable. Start slow with a new batch of seeds so you can figure that question out yourself; it's the only safe way to do it.
With my last batch, it was prolly 14 or 15 seeds - I don't know if that would give me ego loss, but I would prolly be blacked out for 2-3 hours.
I've seen extremely potent seeds before, however, so when I test a new batch, I usually take 6 seeds in a safe setting (no driving or public places).
I'm talking about HBWR. I can't give you a ballpark guess on morning glories -- they're really weak in my area.
I've never gone near that kind of dosing though. If you're not concious to keep your limbs moving, i imagine you could lose one, or more likely, some of your fingers from vasoconscriction.
This was answered a few times in this thread and the previous big and dandy thread -- you should check back for more information and make sure you are aware of the physical side effects. Feel free to ask for more details though.
be safe.
