I'm on the verge of closing this. The thing is, we've pretty much mapped out the entire situation based upon knowledge that we have regarding Methamphetamine. Usage of stimulants of any kind in high dosages can and does lead to paranoia, hallucinations and potential violence or complete mental breakdown. Auditory and Tactile (touch) hallucinations are actually the hallmark of high-dose Amphetamine intoxication. The same thing does not happen to say, Opioid addicts. I'm not saying we're superior, but we don't generally lose touch with reality beyond the euphoria of the drug.
You really need to be careful man. I know the situation is kind of comical to you, but you really need to examine all possible outcomes from these decisions. That exterminator could easily have been an anti-drug crusader who wants to call the cops on you simply to cause you pain. You could end up in the streets looking for those voices, leading to handcuffs and felony possession charges. I know it's a compulsive thing. I'm not saying it's easy, but please try to limit your Meth usage to more reasonable level. What is reasonable?
Reasonable in my opinion, and this is just like Opioid addiction, involves being able to complete all of the basic tasks that are required to live a normal, fairly stable life. This means going to work, personal hygiene, at least 4 hours of actual sleep a night. This might mean 8 hours of "sort-of-sleep" when you're coming down, but you need it. You need to eat and stay hydrated. If you don't do these things, you enter a downward spiral into fully-compulsive usage and eventual, severe consequences as a result.
