Is the Fact That Meth Lets People Have No or Little Sleep for Like a Week Itself Bad for the Body?

Like I was wonder if maybe not sleeping for like 6 days eating nothing but surgery foods and running around looking for meth is bad for ones health.

I mean I know there is no research but I get the feeling that neglecting sleep for long periods of time with little nutrition and constantly repeating this cycle is bad for you. But I have to just go by a gut feeling that maybe food and sleep are necessary and maybe the worst side effect of Meth is not the drugs chemicals but the fat it causes people to do that.
