crushing viagra

Can Viagra be crushed.  I am proscribed 25mg of viagra which I buy as 50mg pills to save money and cut in half.  Cutting a viagra in half is not easy because they are hard coated and not scored (and oddly shaped).  I find that 25mg is a little too much since it has side effects (a low blood pressure feeling, even though I don't think my blood pressure is really low).  I have tried cutting the 50mg into fourth (very difficult), but this seems like a little too little.  I would like to cut it into thirds, but this is clearly impossible.  So.  Can I crush the pill and weigh it out into thirds.  I understand there are two possible reasons why I should not.  (1)  It is a time released medication and the coating is important to keep the medication from coming into my blood stream too fast.  I don't believe this is the case with Viagra.  (2)  The medication deteriorates when exposed   to air (oxidizes) and would lose potency if crushed.  This I don't know and am asking about.  Thank you.    BTW:  I entered this question into another ED related forum and it seemed to dissappear.  If I am repeating myself, I apologize.

Not a doctor, but I have taken crushed Levitra and Viagra to speed up effect. Otherwise my slow digestion takes over an hour for the effect to begin. The only thing I have noticed is that the flushing effect begins in about 15 mins and in less than 30 mins the benefit is apparent.
I'd like to hear if taking a crushed tablet is harmful. I don't need the benefit to last four hours, I take the medicine right before my wife and I go to bed.

If you just need a small boost in your sex life why not try something that is more natual and not a drug, you could try erection tea or the 5G's you can Google both and look for pegym, or you can try cayenne and garlic as a help as well, there lots of info on these just Google them cayenne for ED and garlic for ED, and these well be better for you than Viagra.
Good Luck
