I'm currently high off my ass on opiate painkillers for a torn ligament in my knee. Bizarrely, I've not felt tired since taking them, and as far as the dozen people I've spoken to on Skype can tell, I'm still totally rational. My skin is itching lightly, and I have the uncontrollable urge to bounce my leg up and down repetitively. I am most definitely feeling euphoric, though not to a degree where I feel emotionally unstable. I'm also shivering slightly. Overall, it's quite a pleasant feeling, and I'd be quite interested to see what my art would look like if I were currently in a position to draw.
