The rush you get from injecting is overwhelming - check out pnp vids on sites like Pornhub, and you can see people get the “meth cough” when it kicks in (lungs feel ice cold) and then get the crazed look in their eyes.
After that immediate super rush, I would always start sweating profusely and my mind immediately went to sex. I recorded messages on sex lines to meet strangers, would cruise the apps (especially Nasty Kink Pigs). For the next two days I would constantly go on pr0n sites to jerk off - and I mean nonstop.
But...I’d immediately lose my hard on (meth causes decreased blood flow to the dick, and also makes it difficult to piss because the tubes just go into spasm). It’s a bottom’s dream drug because you can just get fucked endlessly for a couple of days, and no one cares about your limp dick in the sling.
For me, I didn’t like smoking (“what will it do to my lungs?”), so I went straight to injecting meth. Easy to get syringes/ filters/sterile saline from pharmacies or the local harm reduction center. Had some friends who were experienced slammers, and showed me how to backload and filter syringes to keep from injecting larger particulates. Lost weight because I just had no appetite - it wasn’t that food wasn’t appealing, I just had no hunger.
I lasted about a year on it and one day just decided that it was taking too much time from life to come down from. I could see myself becoming irritable and generally emotionally labile in my daily life. I wasn’t working at the time (disability), so I had plenty of time to slam and recover without any responsibilities, but it was taking 3-4, then more like 5-6 days of being strung out and exhausted afterwards.
For me, I think I had a resilience that allowed me to focus more on the latter bad effects. I realized I was getting older (50s), and this just wasn’t sustainable. Never went to rehab or meth support groups. I just kept on increasing intervals between slamming and “forcing” myself to think about how badly I felt recovering.
Every time I fantasize about using now, I immediately think, “yeah, but remember how shitty you felt afterwards for days?” There has to be that counterpoint for the incredible feeling of “being on top of your game” while using.
