Sure. The relief is actually free ; though once every 10 uses we'll spike your dopamine-related brain centers to 1,100% activation for a quick second while flashing a peptide sponsor ad, then back to normal.

You can of course, also not get the spike ads, by subscribing to Premium. Just have a quick look at this animated QR code, it will explain better than I can in writing.

Edit: there used to be an OSS app you could use where you actually pick what you want activated in your brain and when, but it's been banned after one of the commercial producers's investors convinced the government that this technology was too powerful, so only government-approved apps are allowed now, and an emergency vote passed the BrainControl law authorizing logging of all visual stimuli you look at, in order to protect your children.
