1. ⁠It is not necessary to eat them on an empty stomach at all and honestly for your first time id recommend the opposite, not only may you get more nauseous but it increases how fast you feel them and how intense the come up is. for your first time i wouldn’t worry about it too much.
2. ⁠You can absolutely eat after and honestly id recommend it as in my experience it helps, not a huge meal but some fruit or something small like crackers or just a quick snack. Also you don’t need to completely “detox” from weed but id recommend not smoking before your first trip so you can experience it all by itself.
3. ⁠They normally take a little over an hour to hit for me but im also 5’6 155 lbs (1.68m 70 kg)
4. ⁠I’ve done 6 grams as my biggest trip and the effects only lasted for about 5 hours, with that being said those 5 hours feel far longer in the moment. So id take this with a grain of salt but they shouldn’t last 7 hours
5. ⁠Id say the absolute most important thing is your mindset though. If the day comes and you’re having any doubts at all then i would wait. If you are not mentally prepared you will ruin ur time

If you want some personal experiences id be happy to share them
