One other way to prepare before the psychedelic experience begins is to have a “backup sitter,” recommends Grotfeldt. While it’s not necessary to have two sitters for one tripping person, telling someone you trust what you’ll be doing can be crucial if an emergency situation arises. While sitters have to be prepared to call emergency services as a last resort if something seriously dangerous goes down, sometimes all you need is a backup sitter to support you and help you think of solutions from another perspective. Another situation where a backup sitter could come in handy is if you’re sitting for someone who is physically much larger than you, and they begin to act violently (breaking things, screaming). In this case, you’ll want to have a backup sitter on call who is large enough to help the voyager work through these feelings. Basically, having someone to call or text when things get questionable can help you to make the safest choices for those you’re sitting.
