Ahh, my mistake. I was referring to viagra. When I do treat myself, I buy the 100mg and break them in to quarters. Better value that way.That’s a big dose for cialis. Dose for as needed use usually is 10 to start (tho 5 works for many). Max is apparently 20. Daily use is 2.5-5 mg. I’m not sure but I think 25 mg is usual starting dose of viagra.
