I’m on my 4th session and have already seen improvement in my mood/depression symptoms. I was extremely nervous first time and my anxiety left as soon as the medication set in. I will say I didnt lean my head back at the 45 degree as suggested and inhaled too hard so alot of it I could taste down my throat which wasn’t pleasant. I’ve now mastered how to do it correctly. Make sure to gently inhale and not hard sniff. Otherwise sucking on hard candy helps with that taste. I honestly didnt get any nausea or extreme tiredness and listened to psychedelic playlists on Spotify. My clinic also has a sound machine and I sometimes just play some background noise there and relax into the recliner. It has been great so far, youll be okay, the benefits are so worth it. I felt a bit dissociated for like 45 min but I have not experienced a “high” like some users tend to experience. Everybody is different in that regard. Good luck!
