Fighting jetlag

From the New Scientist
Only works on jetlag due to eastbound flights though….

Another interesting effect of sildenafil…

I guess this will be a common excuse used by jetsetting guys when wives find little blue pills amongst their belongings.

(Sildenafil was originally developed for angina, but they found an interesting side-effect, the rest is history. There is also more recent research indicating potential applicability in improving energy balance (anti-obesity), as well as certain cardiovascular indications)
