No, there isn't a way to speed up the effects of Viagra. These tablets need to be processed in your digestive system to take effect and even if you crush or chew the pill, the time it takes for your body to fully process the pill stays about the same.
Like with many medications, if you take it with food, it will take your digestive system longer to fully digest the pill since it's also processing whatever you recently eat. If you are trying to get the fastest results from Viagra, it should be taken on an empty stomach or after eating a small amount of food.
