Couldn't skate at all on robotussin, couldn't even move on ketamine.
I never really liked skating while drinking to be honest. Just get hamm'd after the session.
Hallucinogenics gave me too much anxiety to do anything.
Amphetamines made me super hyped but made my muscles real tense and crunchy. Drank tons of water. Got 5th place in a high ollie contest on adderall.
Skating on a small dose of benzos was nice cuz I didn't think about anything and I felt a little loose and floaty, but almost always too too much and would rather just stay home and take a nap.
Skating on opiates was fun when I was heavily addicted - if I could just take enough to get a fix, I'd be happy enough and well enough to want to go shred. But being sick I obviously couldn't get out of bed, and sometimes I'd do too much right before I was trying to leave the house and I'd fuck up my plans.
Always preferred skating sober and just getting fucked up afterward, helps numb the pain of slams and the emotional pain of failed tricks. Now that I'm sober I honestly don't skate nearly as much, I just try to drink more water, take all sorts of weird anti-inflammatories, and ice my back. Foam roll on occasion.
