M.J.
You know, I felt the exact same way as you & I can tell you what I did which I know is not popular with exclusive BF moms, but it worked for us. I breastfed from the time I got home from work until the time I went back to work in the morning & in the daytimes when my kids were at the sitter's they got only formula. In the beginning I had some trouble with being too full, but my body adjusted really quickly. Like I said, I know it's not terribly popular, but it worked for us really well for several months with both kids. Best of luck to you!!
