you should use indina viagra " kaamneg" my friend . this is better substitute of viagra and has no side effects et al.its not herbal but i think they have put some domperidone and some herbal stuff to make side effects go away. great experience with it. they provide is online too.
I've never needed viagra for but I use it recreationally for fun so I just buy it online here without a prescription here http://www.sarms1.com/liquivia
