Report

After a few moments of inhalation, I remember feeling super relaxed. I was constantly feeling a bit disorientated and forgetting what was going on. The doctors inserted the butterfly needle into my arm and I looked away and tried to focus. I still felt something, but not as intense. I then felt so proud of myself for being able to give blood, as I hadn't in ages due to my needle phobia.

I remember getting up and feeling a little bit dizzy and kind of clumsy, and in the mood for some more so I couldn't help but take a few final hits. I reported no euphoria per se, but certainly a lot of sedation and an overall feeling of contentment.
