What have I done?

[RoboCop]

I have been smoking salvia extract pretty often now, either monthly or weekly, usually it goes well, and I learn from the trip and have been getting to enjoy it. However, have any of you gotten one of those trips where right after taking that last hit you want to take it all back? Like nevermind I don't want to do this, I shouldn't have took that hit, and end up trying to fight the salvia trip, like if you ignore it it will go away, lol. Sometimes I get those regretful trips, they come out of nowhere, usually when I am not lying down comfortably.
This is the only drug where I never know what to expect sometimes its good, and I easily flow with the trip, while others I just wish I could abort them right away. There not really bad trips, I don't freak out just very uncomfortable. Even though I am a constant user when I get this feeling I often forget the peak only lasts 3-5 minutes, and I start thinking to myself like it is going to last for hours.
