What's up Popper,
I just tripped for the first time two days ago, you can check my report in the Trip Reports section. I recommend you sit down before your trip and ask yourself what you want to gain from your trip. Why are you doing it? Give yourself a reason and go into your trip with that in the back of your mind and just let go. Just flow and get ready for visuals, color, contrast, and intense emotion shifting. All controlled, for me at least, but just keep an eye on your thoughts and if you feel it going south check yourself and change your mindset by breathing deep and taking yourself to a good place.
enjoy it amigo,

Also, if you start to feel like you're getting to overwhelmed and you want it to end just let go of that feeling by breathing through it and shake that feeling and just try to get through the emotion because the moment will pass soon. The acid trip is all about endurance in my mind. It's like the difference between the 40 yard dash and a marathon, pace yourself and just take the emotion and visuals as they come. You will love it!
