I was hooked on Meth for about three years. The first year seemed exciting and more for a party-experience. We'd smoke it, snort it, eat it, do hot rails & put it in our drinks. The high was so intense the first day on it each use, I would bounce around the entire house unable to focus on a single project. It would half-dilate the pupils and my pupils would react to light. I had to hide from my parents and other people quite often due to paranoia but I never went overboard and thought people were "out to get me." or the cops were after me. I ended a ride after 8 crazy days of smoking grams away, sluggish and tired, I was also framing houses at the time and was going to work on it after being up for days, extremely dangerous. Either way it was fun then and it wasn't so bad. By the end of the first year, in December, I injected for the first time. Once you inject crystal, there's no other way to do it. An entire week goes by like a flash, day turns to night and back to day in what feels like an hour. My pupils overtook my blue iris by then and they would not react to light, my eyes were literally black with no color. You can stare into the sun and still your pupils would remain dilated with injection. With 99% Bioavailability, the rush comes on strong, a matter of seconds. It begins at the soles of your feet and like a wave shoots up your legs, spine and finally to the top of your head. It literally feels like your hair is tingling for an half hour after the initial rush, then after that say goodbye to reality because you're strapped into a fucking roller-coaster of a ride. The high lasted longer, was much more intense and seemed cheaper. As opposed to feeling tired by day 2 and 3 from smoking meth, shooting meth had you feeling like the first hour of use for days. Hallucinations would set it the first night, shadows moving, severe jaw clenching & formication by day three, I never felt the skin crawling sensation with any other use, only injection. It was hell on my body and I've spent entire nights sitting in a chair afraid to move after sudden heart arrhythmias. Heart rate increases. 120 BPM resting, veins disappear from hypotension which is a contradiction to the high heart rate easily causing Cardiac Arrest. Overdose is easy, if you redose 20-30 units every 5 hours chasing the rush then it's very possible to O.D. In that life though you don't really care if you live or die, the idea of something somebody cooked up in their trunk going straight to your heart is rolling the dice. We'd always joke about it being the last time, you either die or get high. The highest I've dosed on my own is 35 Units of pure ice, see-through glass which is too much. 30 is too much, hell, if it's good enough even 20 is too much. Early on I let somebody dose me and they were so fried at the time that they forgot to split 60 units into two 30's. He ended up giving me all of the 60 without even realizing and I knew nothing about unit measurements in a needle at the time, death in a syringe right there, my thoughts vanished, I had to sit down, I felt like a ghost, weightless, fading. I thank God I'm still here and clean, it was a dark time in my life and those seemingly harmless days the first year turned into a very dark, slippery-slope addiction in the two that followed. I lost my job, my teeth, my motivation, my hope, my desires, my dreams. It left me broken for a long time and I've tried it a few times since just smoking a little or snorting a bit but it does nothing for me now days, I'll always feel like I lost something with Intravenous Meth, something I'll never get back.
