Honestly, sometimes I think "sceptic" is just another word for idiot. Sometimes sceptics are the biggest suckers of all.
* if it's all placebo effect, why don't you give up methadone by using a placebo? The study was placebo controlled, you might have noticed (but didn't)
* "I took a gram of vitamin C and it didn't help me" - shit, I took a tiny chip off an aspirin and it didn't cure my headache - could it be that aspirin doesn't work?
* ascorbate destroys opiate receptors - that'll be why all animals except primates and gineau pigs are in pain all the time, because they make the equivelant of a human taking 10-20g IV ascorbate daily. You can do anything in a testtube - did you see that they were pumping gases into the setup, and it only worked when the solution was oxygenated? The oxygen in blood is bound up in hemoglobin in RBC, not a free gas. I don't even see the point of the experiment, unless a drug company was paying to discredit the competition. Also, it was just a old theory that addiction increases receptors, more recent findings are that it makes fewer and smaller receptors which do not work properly due to exogenous opiate binding and need to be replaced (which is why you need the protein - whey protein is a good idea for this). Actually, if ascorbate did destroy these old, munted receptors it would speed up their replacement - but I don't think it does.
I've had the experience of injected vitamin C relieving withdrawals and sending me to a solid sleep for a few hours. If a placebo could do this, I'd take it. What would be wrong with that? However, bear in mind that IV vitamin C has recently cured a case of terminal leukaemia and a case of end-stage pneumonia in New Zealand. In both cases the patients were unconscious (in coma) and on life support. How would a placebo work then? Also, mr Static Mind, do you think that animals like rats get placebo responses? How do you think that works? Indeed, do you know what you mean by placebo? How, exactly, does it work? Is there some kind of vital healing energy or qi that is turned on? But I thought you were a sceptic!
Isn't it simpler to accept that something works as described, as used by hundreds of doctors and thousands of patients over decades, than to go to extremes to deny it? What about Occam's razor?
But if you're going to do it, for gods sake do it properly - as Michael Jackson said, "Don't Stop Till You Get Enough".
