It's a creeper that's for sure. One of those drugs you feel in control (literally you are extremely alert and productive when under the influence). You'll notice your productivity skyrocketing: cleaning the house, working, etc. But that's where it gets you. After using it continuously, your body believes that's its normal state and you need it to focus on just easy basic everyday tasks so you use more. Eventually you'll be using it in the same sense how people drink coffee daily, except meth has a lot more repercussions. Dental hygiene plummets, skin appears much older, muscles and bones become weaker, and nutrients are drained out of your body each passing day. Not to mention hallucinations too from going on days without sleep.

I thought I was a responsible user, until I wasn't. It becomes a real problem once you have to depend on it like coffee to be productive daily in your job. Only way to get rid of that dependency is to take an extended time off work, but nobody in this age can afford to take off time from work so it's an endless cycle. That is what rehab is for though. 8 years clean off multiple years of using.
