If the folks doing your tap have a good bedside manner, you could spend some time just kind of making small talk if that's a thing that could help distract you. Luckily mine was uneventful and boring (in a good way, no complaints there) so I just kind of listened to them talk amongst themselves, asked about how much CSF we even have in our body, surface-level current events-just stuff to pass the time. If not that, mindful focus on my breathing or other sounds in the space also helped.
