You may have already tried this route but when i was uninsured, i always asked for as many samples as i could get!

This one prescriber always told me she didn't have any of what i needed. Then one day i brought in a lengthy form from the drug company for her to fill out so i could get the meds for free. She took one look at it and then . . .surprise! She found a whole stash of $500 a month meds in her closet

(and i soon got a new doc!)
