No need to do any heroic dosage. How much are you planning and in what form? I ask because if you just want to relax, weed is fine as a sedative. Shrooms will make you feel more, not less, so expect this and the possibility of deep introspection depending on how much you take.
Context is key. Relax into the experience. Expect your focus and attention to sharpen. Odd things will catch and capture your attention, like trees, leaves blowing, insects etc. You may feel like static images start to slowly move like a Lava lamp as it starts working. I love listening to philosophy or music because it feels like your brain is operating on a different level to normal. Everything seems a lot deeper and more significant.
Expect the possibility of a slight discomfort in your stomach, but easily manageable if your prepare for it.
There really is nothing to fear below 3g. I took 1g first time around just to feel it out and even then the experience was very pleasant. Enjoy!
