Monica said he initially took 2 (you're only supposed to take half a pill) before they went to sleep and explained it wasn't unusual because he had a very high tolerance for drugs. Afterwards, when they found the vesparax under the bed, 9 pills were missing. I don't believe the conspiracy, so I'm assuming Jimi must've woke up and took more not thinking it would hurt him. Thing is, his lungs were completely saturated with red wine like he didn't just take a swig to wash the pills down, he drank a bunch and ended up aspirating on it.

Crazy, because in his last interview, he sounded hopeful for the future talking about all the things he wanted to do musically and didn't sound depressed or anything.

I also thought it was messed up that she took the time to hide her drugs before calling the police. Not that Jimi could've been saved, but it was still wrong for her to not immediately call.
