Welcome to Bluelight!
I think that doses below 1 gram of dried mushrooms are very weak. The experience can be summed up easily as follows: I want and I can not.
If you want to have a first experience with dried mushrooms, I recommend you start with 2 grams. You will experience moderate psychedelic effects but it should not be overwhelming at all. I do not know the "golden-topped" mushrooms, but make sure they are Psylocibe Cubensis and not another strain like the Semilanceata since they are much more powerful.
2 grams of Cubensis is a standard dose, you will have visual effects such as changes in hue and tracers, with higher doses 4g + is another story.
Find a place where you feel comfortable, think that sometimes the presence of other people can be uncomfortable, especially if they are not known. I think the beach can be a good place as long as it's a quiet day and with clear skies. Personally I like the forest more because I can fall in love with the vast nature and navigate through its infinite forms. 8)
Have you thought about taking it day or night? Are you going to take it alone or accompanied? They are important aspects.
Finally, I recommend you to fast (at least 6-8 hours) and take the day off to devote to what you really want. Charge your phone with good music and get some good headphones, I think it is essential if you want to travel alone.
Mushrooms can be a very powerful experience, even 2 grams for someone without any tolerance to psychedelics can be revealing in many ways.
Be patient and act with care and moderation, let yourself be carried away by the experience and before a psoible situation of fear for what is happening I think that the best tool is to have an open mind.
Do you have access to any benzodiazepine? They are very useful to eliminate part of the body burden produced by the Psychedelics. 2.5mg-5mg of Diazepan 30 minutes before eating the magic mushrooms can help reduce anxiety and vasoconstriction.
A beer would also be helpful.
I hope you have a good trip. Here we are for what you need.
