I am beginning to think that with weed, any is too much, however I only have a few experiences with it, which is odd considering my seasoned history with many other drugs. I've never smoked weed by myself, and I think if I was by myself and in a good and positive headspace, I would very much enjoy. I definitely can appreciate its potential to bring forth massive creativity and allow for unique perspectives on the mundane of life, despite a couple very anxious and excited experiences. It has felt much more intoxicating than almost any other drug I've done, and with a very stimulating edge, making it a frightening one for me in public settings. But again, I really do think it could be of great personal potential for me.
With booze, it is too much when the warm and slightly tingly stomach becomes quite suddenly nauseated and intent on vomiting.
With amphetamines, though I've never done the stay-up-all-night binges for days at a time, I know I've had too much when I begin feeling transient paranoia, experiencing bruxism, feeling as if I could do anything yet being very beat and very tired, feeling too hot, often to wake up after crashing in heavy sweat with the most panic-like dysphoria, and headache. (I take tramadol daily, too, and at none too modest doses, so even a moderate dose can seem to incur certain very uncomfortable effects.)
With the GABAergic sedative-hypnotics, including benzo's, of course, I never seem to feel as if there are any lines, BUT I am quite tolerant to their effects considering fairly thick dependence. And with opiates, I've never even become truly nauseated - I tolerate them quite well without really any undesirable effects often described from others; the first time with hydrocodone, ever, I got a bit too hot and got kind of a headache-feeling, but other than that, nothing bad, even at relatively higher doses.
And, with nicotine, I know I've had enough if I don't want a cigarette or if I want to stop smoking the one in hand.
