I have done a little research, and while this is likely not the best idea for most people, it seems to help for me. Meth works in your brain like heroin, in theory keeping you from withdrawals, but it doesn't do that, i keep you awake, as we have ben moving w/my fiance sick I have done most everything, and though we are not done, we are 1 truckload away! but seeing as i have had to pack a house alone load and unload a truck, alone, I got some meth. at first it seemed like i was doing more, but in reality i was doing the heroin every time i started to get sick, since i wasn't sleeping, every 6 or so hours, i did some.
But since i was up, and working for 3 days, i slept 27 hours straight, obviously I woke up sick and did a little, but less than normal, Im thinking if i drug myself to sleep in a couple hours, I will be closing in on 48 hours with 1 dose, that would mean i need 1 a day, $2.20 USD, thats pretty low, so thats my plan for now, as i want to get as low as possible before i leave.
