What happens if you do meth?

Usually users of methamphetamine's act very strung out. They can stay up for days at a time, like 3-7 days at a time. They sometimes talk & can't stop talking about the most random stuff. They'll be talking about one thing one minute, & the next something totally unrelated. Also, they get very angry, hostile & violent. Not all users, but generally when their not high anymore, they get very irritable & need more meth to stay "happy" & not pissed at the world. When they are finally done with their "run", they could potentially sleep for 3-5 days at a time & during those 3-5 days, they most likely will be getting up randomly & eating like they haven't eaten in 2 weeks! They generally like to eat sweet sugary things because of what the chemicals in meth do to their system. The sugar releases dopamine in their system, a type of natural pain killer, & they eat sugary substances because they associate the sugar with feeling better since their not high & are feeling bad from not using for those couple days.

I hope this helps you..... btw, there is a lot of info on line about it too.
