1st time, coffee & stomach concerns

Hi everyone, My best friend and I are taking shrooms next week (she has experience in psychedelics), but it’s my first time. After some research my idea is to do 2.5g (input appreciated here). My intention is to explore myself and gain spiritual insight.I’ve done quite a bit of research over the last 6+ months but I still have some questions if you all don’t mind.I drink coffee every morning and get a headache if I skip it, is it ok to do this the day of the trip and should I fast?I’m tough with all pain but stomach pain and nausea are my toughest to work through in my mind. I’ve read making lemon tek can be most beneficial but I don’t know how I would dose that? Do you simply weigh it then chop up your amount and proceed with recipe? My friend in the past just ate hers on a peanut butter sandwich with no problem.I can’t find many articles on the physiological reason it makes people nauseas. Coming from a science background I would like to understand.Should I prepare to be in the bathroom- it seems many don’t experience this but many do. How long do the nausea and cramps last?Our plan is to go to the beach, where it will be mostly deserted, meditate, listen to music and just feel the experience. We will be alone but would have someone drop us off and have a planned pick up. Is this a poor idea? Should we be somewhere confined or with someone around? Will I have some level of awareness towards the end in which I can call my ride? What’s your favorite time of day to begin and end a trip and with different consumption levels how long should I plan to be away?Thanks all via /r/shrooms https://ift.tt/2vfhy4i
