Please stay respectful. This thread is important and absolutely valid and I'm gonna explain why: reports about the taste of N are rare. Generally speaking, not that many members experiment with N before they leave. It's just not a very widespread method because of the financial hurdles that come with it. And if people describe their experience with the taste, it helps us all in preparing for N once we decide to leave. More information is always a good thing. It gives us some insight in what might await us if we decide to drink these bottles. But if we create an atmosphere in this community that discourages people from talking about their experience with N, even when their experience is obvious because we all know that N tastes horribly at least in theory, less people are gonna be motivated to talk about their concerns. It makes it more difficult for us to openly talk about the downsides of methods and therefore obtain first-hand information. For most of us, the taste of N is a very small hurdle but there are people that are very sensitive to bad taste and we should acknowledge that without insulting them in a passive-aggressive way.
So when people talk about their experiences with N the next time - keep in mind we don't get to listen to their stories very often because pretty much nobody survives an attempt anyway(!) - just appreciate that somebody actually takes their time and energy to report their experience. And this here seems like a genuine experience in my opinion.
Regarding the actual topic: sadly, there isn't much you can do to make the taste bearable, unfortunately. I've tried lidocaine spray in the past and it doesn't really work well in my opinion. You can try to make it more sweet by adding syrup but in the worst case you're just gonna increase the volume of the substance and add more flavour to an already nasty substance. Not sure if that's really a desirable outcome. According to the PPH you should try to get the N down as quickly as possible and eat chocolate afterwards. You can also chase N with some alcohol which speeds up the drugs action. But there aren't many safe workarounds at the moment.
