You can repeat your experiments with hydrochloric acid.  It is available in 
paint and hardware stores in industrial grade where it is called "Muriatic 
Acid" and is used to remove lime and scale (it also does a good job of removing 
your skin, clothing, etc. so be careful) .  Out of the bottle it is about pH 
minus 1. If you dilute it (as you probably should) remember the high school 
chem lab warning "add acid to water, never add water to concentrated acid."

    I'm not trying to say that CS doesn't work when taken
    orally! I'm just trying to understand how CS ingestion 
    can be optimised given that the stomach is basically an
    acid bath for food. Fruit goes through the stomach
    very fast but things like milk and meat and fats can
    stay in the stomach for hours and hours. I think its
    fair to say that most of us have food in our stomachs
    most of the time during the day unless we miss a
    meal or eat a very light vegan/vegetarian diet. 
    What I don't know is the PH of a full or partially 
    full stomach.
    
    Maybe most of the CS absorption takes place before
    the stomach?
    
    What I'm doing now is taking a glass of water with
    a small amount (eg, 1 gram) of baking soda a few
    minute before I take the silver. 
    
    The other point you raised about different types
    of acids is very good. I only know that ascorbic 
    acid destroys CS or at least causes violent 
    aggregation.
