Can I sleep on my camping mattress every night?

I am in the Peace Corps and my bed is awful because I get paid $200 a month, I can't buy a new one. I have a NEMO Astro Insulated Sleeping Pad, how long can I sleep on that until it breaks? Also, are there any tips to make it last longer? It is a blow up sleeping pad.
Update: My bed is awful, but because I get paid $200 a month***
