Hi Jboy... I had a 2-oz bottle and was worried about running out of it by taking it internally, but I would have had plenty. I did take it internally with 2 or 3 of the doses... You won't regret ordering it. It's great stuff.
Oh -- and I used it in both eyes for the three days I used it, and my other eye was bright & clear! I think it helped w/ my usual allergy red eyes too... i might try it daily for a while.
