He may not realize this (I think he may, but i dunno), but you aren't dealing with the shit he is so it surprises me that you don't notice what is happening here. Of course it is a placebo solution, but for a man who has had control issues his whole life, this is a way to take back control and is something he needs to get better. It's obvious his anxiety is a result of this illness he couldn't google a cure for over night, coupled with lack of sleep for an extended period of time due to extreme discomfort and for someone who needs to feel in control it broke him a bit, but if something like this helps him put the pieces together why shit on it?
Also, LOL at anyone thinking .25mg will lead to addiction or him wanting to take more. After 1-2 days max the affects of this are almost nonexistent. I doubt he ever increases from here. Assuming his condition doesn't worsen, eventually he's going to think that he has tricked his mind and doesn't need to take it anymore, in reality it will have been the point where he has finally taken back control.
Get well buddy, I'm pulling for you. Fuck these guys, do what makes you feel better.
