In regard to the bitter taste of the N, a mouthwash called "Botot" numbs the tongue so the N is easier to take (perhaps whiskey would have the same effect?). FYI, six people that I know of on the Exit forum used N successfully between 2013 and 2015. Most used 12 to 15 grams and one used 18. Three lived alone, two went to a hotel and I don't know about one, but they all made sure they were undisturbed and had plenty of time. It took one person 3 to 5 minutes to fall asleep and 45 to exit. When they were gone, I either talked to a family member and/or read their obituaries. It was very sad.
Question: What is "meto"? Several people used Motilium/Domperidone for the antiemetic. One even used Dramamine.
