Was reading through some older threads and noted that buried in one was a brief mention of splitting tabs.
A personal friend (real life, not like the friendly blonde Candi who haunts my dreams), actually started doing this and mentioned it to me.
I mentioned it to someone I e-mail with, so three of us have been doing this with 20mg tadalafil.
All of us use generic tadalafil "hard" tablets. Two of us from Vipro, the third is made by Cipla. All of us have no problem with the splitting.
BUT, you have to buy a pill splitter from a local pharmacy, discount store -- heck I don't care where you buy it from -- if your local tire store also sells pill splitters, so be it! There are several different types. The cheapies are around $3 USD and the more expensive a buck or two more. I'd suggest you go for the more expensive.
If you are doing tadalafil, some of the splitters seem made for the oval-shaped tabs -- they have sort of a triangle-shaped cutting area with a V-shaped holder, which makes cutting the tadalafil easier.
I first tried to save the few bucks on a pill splitter and tried doing this with a knife on the kitchen cutting board. Made a big mess. I mean the tab crumbled so bad, I thought "hey, I might as well try to snort this (just joking, don't try snorting it).
Anyway, the 20 mg tadalafil supposedly last 36 hours. And they do. But I find if I split them in half -- about a 10mg. dose -- it lasts me at least 24 hours.
When I say 36 or 24 hours, that means I am good for multiple "sessions" during that time.
The friend who gave me the original idea did it because 20 mg gives him horrible headaches. If he does 10 mg and drinks a fair amount of water, he has no problems.
Anyway, 10 mg works great and doubles your supply. You all might want to give it a try, all it will cost you is a few dollars for a pill splitter.
Oh, guess I should mention, I can be a paranoid sort, so, as most of you know, you take the darn pills and you DON'T feel anything until something gets you going.
So, even though I've been taking these things for more than a year, sometimes I get a bit concerned and even though I know better, I often will pop the second half of the pill 30 minutes later, since I don't feel anything and am afraid of not "being ready." I'm working on curbing my paranoid thoughts.
