Hi Teebs,
I have had similar experiences. I was at 10 mg of Prozac and went upto 12.5mg and had some anxiety. It came and went. Don't view this as a set back! I was frustrated as well, but my husband helped me realize that it would pass. And, it did. Are you on the liquid prozac? If you could you titrate to 17.5 mg then 20mg just to make it a bit easier? Also, try to schedule in a couple of appts with your doctor that week as you are increasing the dosage, I always find that helps. Remember how much better you felt after a couple of days on your previous dosage when you feel the anxiety comming on....
Your posts to me when I first started were so encouraging. Keep at it and keep us posted.
Your friend,
