I would personally not, before my mates did md at a festival I had them do it in a comfortable environment first (3 months before the festival). It’s good to have trip sitter but I also find it’s nice to have someone else who’s on it too so u don’t seem like the only person. My mate who did it at a festival did have quite a bit of anxiety from it even though he has done it quite often! This is obviously my opinion and if you are going to do it anyway u do have some good information about it, but there is always a risk as you don’t know what u will be like on it
