Depends on what you're drinking/eating and how often you brush and with what toothpaste.

1. Drink coffee , tea, soda etc everyday and it's going to stain quick. Strong dark Teas can do it in a week or month.
Otherwise with a good brushing regimen, toothpaste and avoidance of staining goods/drinks, the six months each treatment is good for.

2. Brush within 30 minute after each meal or snack?
Don't and you're just letting stains sit.

3. Toothpaste

Colgate Optic White
Hydrogen peroxide
Noticeable even without strips

....

Anyways, really good price on 1 year's worth!
(20 per half year for 1 treatment round)

I've tried different whitening treatments including one my dentist sold me with trays and syringes full of what I assume was some kind of bleach. They all worked temporarily, but due to my heavy coffee drinking and things like tea and wine, that I'm not willing to give up, they never lasted very long, and the syringes left my teeth and gums sensitive. I started keeping a bottle of Hydrogen Peroxide in the shower and after brushing, gargle and leave it in my mouth until I finish my shower. Seems to work pretty good. It's definitely not as white as the treatments, but it cost pennies each time. I also douse my toes before I get out to help prevent athletes foot and toe fungus. I liked it so much I bought a case of HP off Amazon. I go through a bottle in about 2-3 weeks. It's a cheap alternative.

Have you tried switching to sensodyne while whitening? it really does help with sensitivity
