As someone who reeeealllly wanted to do the inert gas method but is opting for something else (CO Charcoal in a tent almost definitely), it is because it's complicated, it's expensive, I don't feel confident in my ability to make a proper exit bag and keep it on my head in the right way during the whole process (if I want to address this concern with a premade hood thingy, thats just another cost and a risk of getting scammed while buying something illegal online from people I don't know, probably using crypto currency which is fucking really hard and annoying for me to use), I'd have to do the deed at home because I wouldn't be able to easily transport a big tank of nitrogen into a hotel or something, and that's a big concern because I don't want my husband to have to find me. The supplies look incredibly suspicious - I mean, if I had to hide a tank of nitrogen, I think I could do it in the basement, but the fear that my husband would see it is real, as it is large, and if it was seen at all, out of the corner of his eye or something, he would most definitely check it out because, wtf is that thing, it looks conspicuous as fuck lol. It just adds a lot of complication, and I still have the fear that I don't really understand the process. I am worried the tank of inert gas that I buy won't be "good" enough (you buy the tank based on how much volume it has, and you can't actually ever know how much actual Nitrogen in PPM is in there apparently). I use the word, apparently, a lot when discussing this method because I NEVER ACTUALLY KNOW ANYTHING or feel truly confident that the information is accurate. Also, even just ordering the tank to my house, like, what if my husband was home / the one who answers the door, and sees this massive heavy package with (probably) warning labels all over it. How would I explain what it was? I could go to a welding store and try to buy one, but I am a fairly young woman and I don't think they would sell it to me and believe I was a welder, so that gives me a lot of anxiety. There's just a lot of moving parts to the whole process.
Another thing that pushed me away, was @Vizzy who was a user here who successfully CTB. He has a lot of information in his threads about exactly how to set up inert gas with exit bag or hood. I was using all his information to learn how to do this successfully because he has photos and lays the whole thing out in a nearly step-by-step process that simplifies the whole thing - it was all very detailed and he seemed super confident - if you go around asking for info about inert gas method, I'm sure his stuff will be linked because it is considered a valuable resource on SaSu. But then I read his "Goodbye" thread and saw that he ended up using SN, and that made me extremely concerned. I was like, if he has this amazing set up for Inert Gas, why is he opting for SN? Especially when he stated explicitly, several times, that inert gas was his first choice and first attempt method. It was like, he set up all this information and stuff, has this amazing set up, and then randomly in his goodbye thread says "ok, taking my SN now, bye" and I was like, wait what? what happened to the inert gas? and I still don't fucking know.
However, I have been informed by another user that there were apparently photos of Vizzy's body, and he was wearing the hood, so that user suggested that maybe the SN made him vomit and THEN he used inert gas as the "real" method. But still, in this case, then why didn't he opt for that initially? Maybe he was doubling up on methods or something to ensure success, but I can't find the information in his many many threads. It just felt really wrong to be using this guys information as my step by step guide, when he ended up taking SN and not even using it... like, to my logic, something must have went wrong... and that worried me a lot.
