Gummi Clutch I don't drink alcohol for the most part... I have however taken a Vitamin C pill every day throughout college and have seen the amount of colds I have caught and suffered through in college reduced from 28 in my high school years to only 3 in my college years. Of course, also since the week before the first day of my first semester in college, I have also consistently taken Acidophilus probiotic chewables, one Cholest-Off every day with a meal, had more sleep in college than in high school, was older and exposed to older students with more mature immune systems and somewhat better habits, etc.
I don't know which is the factor to go by, but I didn't take a Vitamin C pill today for the first time in years. Also, I stopped taking Vitamin D pills in 2014 after my blood test showed I had a hypercalcemia factor of ~1.0 mm/dl of calcium above the normal upper boundary.
The problem with oxalate stones is that most foods do contain oxalate, especially healthy foods.
