Word is that it started during History tour. However, in that case a real anesthesiologist was on the job and real medical monitoring equipment was around to keep things safe. HOWEVER, turns out the alleged anesthesiologist who was administering the propofol at that time had some drug addictions of his own (sigh) AND he was involved in unscrupulous insurance practices that caused him his license for 3 years. During a trial for some other doctor under investigation, apparently it was told that this same anesthesiologist once claimed he gave Michael so much propofol one time (during HIstory tour) that Michael collapsed afterwards (I'm guessing after he awoke Michael cuz he surely couldn't collapse if he was knocked out). Anyhoo, there's quite a history with some of these "doctors" Michael was involved with. I can imagine it's taking some time for the authorities to get thru it all...depending on how far back they dig. sigh
I don't there's any way anyone could know just how often he may have been getting this unless whoever administered it spills. Maybe it wasn't every night. Murray came on the scene in early May so perhaps it started around that time. :dntknw:
Apparently, it's been said by a few ppl that he said none of that stuff worked for him...or if it had, it eventually stopped working. This isn't uncommon for insomniacs. Their bodies get used to one thing so they have to switch to something else or something stronger. Nurse Lee, if anyone believes her, did say she gave Michael some kind of herbal tea or something to help him sleep the night she watched him and he did sleep for about 3 hours. And then he woke up. So herbal treatments, at least whatever she gave him, didn't seem to be working either at that point. I honestly believe he did try everything he could think of before resorting to propofol. I personally feel that whoever introduced Michael to this for the first time years ago and convinced him this was a good idea is the person who started this madness. They are the ones who made Michael feel this was his only option or the best option for him when it shouldn't have been an option at all.
I think it was reported after one of the raids on Murray's offices that they found pamphlets to some kind of sleep center or information on sleeping disorders. So...maybe he was about to go that route or Murray was looking for tips to try out on him. It's weird that out of all the doctors he's had over the years that he never sought one who specialized in sleep disorders...someone who could really possibly help him without putting himself into a temporary coma. Being an insomniac isn't something to be ashamed of so it's kinda sad to think he didn't try the obvious. Who knows? Maybe he did and that failed, too.
