It has been well over a year, but I finally got my hands on a THC tinture again. I had my first swim using them just hours ago. I did my normal Adderall dosage, and 1/3 the recommended tincture dosage.
The swim started very poorly, but I kept with it [insert Sixers joke regarding "trust the process"], and it ended up a very promising swim. Too many little things noticed for me to recall, but hopefully, just as in previous years, what happened before will happen again, and will be expanded upon.
Of the things I remember clearly, the left leg position requires more reeling in, the knee and ankle both consistently hyperextend normally, rather, overextend. Focus on the ankle and knee results in the hip keeping a more proper position, the left joint more correct creating no burden on the right to compensate.
Otherwise, there was some success with freestyle, maintaining a relaxed back through superior shoulder position I have never before been able to swim with. It is a much slower swim, not tweaked to maximize leverage, but the feeling was that the posture was much more "correct."
I'll have to play with dosages and such over the coming week.
Progress, the first time this summer, really. At last!
