Is it true that Viagra and Levitra only last for about 3/4 hours and this new drug lasts all weekend? The logical extension (no pun intended) would be a drug that lasts for a week, month, six months, year etc. I guess that it would be like being 18 again. I understand that the French call it LaWeekend drug.
I still find it hard to believe that anyone actually calls it “the weekend drug”. I thought spammers invented that term to get around subject filters, just like “V.I.A.G.R.A” and “ro-ck ha_rd e,r,ecti0ns”. 
does it actually give you an erection for a weekend, or just make it possible? I would tend to think it would limit ones social life with a 48 h boner - but then perhaps not 
I’m not speaking from experience, here. I’ve read some about these drugs, and I’ve talked to men who’ve used the Pfizer one. The pill does not give you a continuous boner. If you’re mentally aroused, you’ll get a stiffy. If you have sex, and you have an orgasm, the stiffy goes flat as usual. Get aroused again, and twang, there it is again, and so on for up to 4 hours.
Presumably, a man who wasn’t thinking about sex could go through the whole 4 hours without an erection. That’s an unlikely scenario, though. If a fellow didn’t intend to have sex, why would he take the pill?
The L pill lasts longer than the V pill, up to 8 hours. The C claims to be effective for about 36 hours.
