Two cream chargers into a balloon. Deep inhale, hold, exhale, repeat. Within seconds a warm wave of dissociation rolled in. The room seemed to vibrate and sounds developed a wobbling, flanging quality.
For about 30 seconds I experienced a strange recursive thought loop — the feeling that I was about to understand something fundamental about reality, reaching for it, then the thought slipping away. The classic 'wah-wah-wah' auditory effect is surreal.
Back to baseline within 2-3 minutes. Slight lightheadedness then completely normal. Did a few more balloons over the evening with 15+ minutes between each.
Important: always supplement B12 with heavy use, never inhale directly from the charger (frostbite risk), always sit down, and ensure good ventilation. The substance itself is quite safe with these precautions but chronic heavy use can cause nerve damage.
