Acrobat 9 Typewriter increasing file size

Question

I have scanned forms that I need to edit with the Typewriter tool in Acrobat 9 Pro - basically I just need to add a date to the form and then e-mail it.  Evidently I have accidentally clicked some box that I did not want to click, because now when I edit the one-page form (about 70k before editing) and type in any data whatsoever using the Typewriter tool, then save the form, the file balloons to anywhere from 0.6 to 0.9 MB.  Which is crazy, and too large for me to submit.
Right now what I'm having to do is edit the form, save it, print it, and re-scan it.  This is making me nuts.  Does anyone have any suggestions?
I have tried Reduce File Size, the Optimizer, and downsampling, but nothing has worked.  I can't make the file small enough to make a difference.
Thanks,
Beth

Base - 14 fonts
Standard Type 1 Fonts (Standard 14 Fonts)
Fourteen typefaces—known as the standard 14 fonts—have a special significance in PDF documents:
Times (v3) (in regular, italic, bold, and bold italic)
Courier (in regular, oblique, bold and bold oblique)
Helvetica (v3) (in regular, oblique, bold and bold oblique)
Symbol
Zapf Dingbats
These fonts are sometimes called the base fourteen fonts.[34] These fonts, or suitable substitute fonts with the same metrics, must always be available in all PDF readers and so need not be embedded in a PDF.[35] PDF viewers must know about the metrics of these fonts. Other fonts may be substituted if they are not embedded in a PDF.
Helvetica was developed in 1957 by Linotype. Arial was Monotype's attempt to make a font that looked like Helvetica (but without paying licensing fees) and was designed in 1982.
Microsoft didn't want to pay Linotype licensing fees to use Helvetica so it went instead with the cheaper Arial.
Arial is held in disregard by many professional typographers and type enthusiasts, for reasons relating to its similarity to other typefaces and the involvement of Microsoft in its development and distribution.[7] It is reinforced by Arial's apparent status as a de facto Helvetica stand-in, but without paying royalties, or credit, to Helvetica. Arial's glyph widths are nearly identical to those of Helvetica,[7][26] rather than Monotype Grotesque, on which Arial is otherwise based.[7] "But to an experienced designer," writes typographer Mark Simonson, using Arial "was like asking for Jimmy Stewart and getting Rich Little."
