Well the only explanation that i can come up with is you have decidedly reached your limit but then again did you expect to be fine after a three day bender? If you want a technical answer for each of your reactions then im sure there are many people out there that can provide it and im sure there are heaps of posts that have already covered it.
The point i was trying to make it that, as horse pointed out, there are loads of anectodal threads (probably 20,000 - 25,000) about limits and how much to take, etc.
In the end each person has their own limits and drug taking is so user specific in terms of quantity that saying three pills, for example, will not do me any damage, is crap.
Analogous to the current round of cigarette adds : "every pill is doing you damage" the only difference is that we are trying to reduce the damage of nicotine rather than get off it all together.
Please note - i only wanted to reinforce what i looked for on bluelight - i think that concern is definitely warranted in a number of cases here and that these people should seek advice and take a break, myself included. It's always about harm minimisation and prevention of long term and irreparable damage.
