yes, he definitely needs something to protect his stomach from the steroids :(
Also, we didnt know about the 'trial run' either. it was only after the doc increased the dose that he told my husband 'ok, now that you handled a stronger dose, we'll increase it one more to full strength.' wow.
basically, with Temodar, it seems the 42 days are at a low dose. Then, when you start 5 on, 23 off, the dose is increased. If you handle it well then the next time (and future rounds) it's increased to the full strength.
