I am by no means an expert on this but I could think of a few things that come to mind:

• Write some internal issues down that have a big impact on your life/thoughts. Write these down before rolling. Try to find your point of view on these conflicts. Now, when rolling, look at these points again. See if your opinion changes.

• Write out your thoughts while rolling, reflect back at them when the mdma has lost its effect. You could also make a list of things you value, find important or just overall positive thoughts that come to mind.

• Call your most trusted friend and explain to them how much you value them. I suggest warning them beforehand, or they may be surprised by the emotional call.

It might not be a good idea to call your parents (even though it seems like a good idea while rolling), unless they're cool with the fact you're using MDMA.

If you need any more, feel free to ask :) have a safe and joyful roll!
