Only so much

Posted by Miri Barak on October 07, 2004

"The book is dedicated to people under stress who may have low energy or *only so much to give*.
My difficulty is with "only so much to give. Does she mean - that they have a limited energy to give? or something else?

2. in this context:
"It'not your fault if you follow doctor's orders and stil feel drained. You just need a more complete *prescription*. I'll give it to you here".
My question: can I use the word prescription here in the meaning of *solution* or stay with the conventinal meaning?

Thank you so much
