I tried anything to get it to work, but it just won't work.
All i had was with out-of-body, that i just felt realy realy relaxed, but that was just for a few seconds...
I covered my eyes, i put on the friggin head(set)phone, lying on my bed, and put on the dose.
i counted from 100 to 0 while the dose was playing, just to concentrate.
But no.. still no effects...

Still hungry for concentration tips!
