I wouldn't.
Take any typical plastic bottle, fill it one fourth with crude oil. Look at it. This is what the actual bottle is made of, plus packaging and transport.
The bottle itself is essentially refined oil with chemicals added to it, melted and molded in any number of attractive shapes and colors, but there is no escaping the fact that it is basically a handful of oil. And THEN it gets transported from the factory, to the store where you just DROVE to go buy it, or from the suppliers warehouse to your gym, school, hospital... 60 million of these are thrown away every year, not recycled.
That's over 100,000 bottles thrown away PER MINUTE in this country alone.
The situation regarding garbage is stressing Earth's ability to sustain life.

Being careful about what you buy is part of the solution, but when it comes to the things you are in contact with most often and the foods you ingest, plastic water bottles are a scary gamble.
The Pacific Institute estimates that in 2006:
- Producing the bottles for American consumption required the equivalent of more than 17 million barrels of oil, not including the energy for transportation
- Bottling water produced more than 2.5 million tons of carbon dioxide
- It took 3 liters of water to produce 1 liter of bottled water
Energy Required to Make PET Plastic
According to the plastics manufacturing industry, it takes around 3.4 megajoules of energy to make a typical one-liter plastic bottle, cap, and packaging. Making enough plastic to bottle 31.2 billion liters of water required more than 106 billion megajoules of energy. Because a barrel of oil contains around 6 thousand megajoules, the Pacific Institute estimates that the equivalent of more than 17 million barrels of oil were needed to produce these plastic bottles.
Carbon Dioxide Emissions from Consumption of Bottled Water
The manufacture of every ton of PET produces around 3 tons of carbon dioxide (CO2). Bottling water thus created more than 2.5 million tons of CO2 in 2006.
