The first few days were completely awesome. It felt like I wasn't me. It seriously felt as though I was playing a video game, playing as the person who was having a shit time. I really noticed the effects like light-headedness just as I was heading home from buying a big back of charcoal BBQ fuel. Crappy timing. If it'd been 10 minutes earlier, I wouldn't have wasted money buying the stuff, seeing as I was only getting it for the carbon monoxide, generally considered best way to go if you lack both heroin and cyanide.
After a few days, it was just a general, light "I don't really care too much" feeling, which was nice, but it took literally forever to get off, which was annoying. It lowered my sex drive in general, really - even now.
But then, for maybe a month after, the "nothing really matters" started to wear off, but it gave me really intense orgasms, so I had something to occupy myself with to make the world seem better
But now... it's more or less "Normal, except it sort of helps life not be totally shit, but occasionally fails". Still, I'm hoping that upping the dose will give those starting effects again.
On one occasion I missed my dose, and the next morning felt really dizzy and light-headed. I try to always get the repeat filled out early these days.
