For me, TAF does not fix the crash. The only thing I’ve found that works is caffeine.
P84 might be worth experimenting with. *(P84 thread: first use report, since so little has been written about it - #2 by Warren) with P86. In equal amounts it did seem to energize and counterbalance the sedative effects of P86, but it seemed to diminish the positive aspects of P86 as well.
Be sure to post if anybody finds anything that helps with the crash. I wonder if P86 causes this tiredness by depressing the Sympathetic Nervous System in favor of the Parasympathetic. That would also help explain the attraction it causes. *
