Yes, you certainly can 
The more often you inflate the more your internal organs will become accustomed to being stretched, so you can fit more inside. Inflate every day for a month and you will soon notice a difference, I did and continue to do it to this day (for over 2 years.) Your patience will definitely pay off in the long term.
Just remember to take it slow and try and push through any discomfort to stretch yourself further. If that discomfort turns into actual pain stop the flow immediately and flush yourself out.
Hope this helps.
