Seems most of the responses on this thread, people haven't noted that it is not flubromazepam but a variant ending in "olam".
Though similar, you are right that there seems to be more side-effects with flub'LAM. The 'epam variant is very clean and very few side-effects. The high is much more pleasant and crisper, not so much "brain fog" in the high as 'LAM (or even more so, Phenazepam if you've tried that). As MDB said the benzo is one of the lushest and surprised it's received such little attention - blissful mood-lifting effect, nice feeling of muscular relaxation. Better/stronger than etiz, and much more long lasting; as pointed it it will last anything from 20-30 hours. Only drawback with it really is the onset is pretty slow, can take 1-2 hours before you feel anything at all.
