Every spring and fall I feel the same way you do. I posted a few weeks ago about the same feeling of fluid in my ears. The fluid eventually drained on its own, but I still have that drunk woozy feeling. It has been happening at this time of the year, every year, for the past 6 or 7 years and it hasn't killed me yet :) If you doctor thinks that you actually have an infection and that antibiotics will clear it up faster, then by all means, try to feel comfortable taking them.
Hope this helps <3
