How to improve roll in 7 days?

hey guys, so in a weeks time I'm gonna be trying MDMA for my 4th time. as ive previously commented and posted about, the last 3 times haven't felt any of the euphoria really. especially the 3rd time but that was wrong set.

this time its 7 days out, I stopped smoking cigarettes about 10 days ago, started taking multi vitamin supplements about 4 days ago and fish oil supplements.

but I have had problems sleeping recently, even 8 hrs i dont feel well rested much. and then i've been up and down with my mood because of the tiredness.

I do feel better this morning, got some things to look forward to later and then in 2 days my friends will join with me that I hope gives me a big boost.

is there anything else I can do to improve my chances of a good roll? I want more than a body high this time, i want a full on euphoria mind blowing party!

cheers
