Ok, my sanity is gone. For the past week, Lex has been waking up 8-9 times each night

We are on a 3.5-4 hour EASY and struggling during the day to get in naps that are longer than 45 minutes (problem since 2 mo old). We have been working toward less nightwakings for 2 months now, (in July she was very sick, got into a horrible bad habit). We were hovering around 2-3 wakings and 2 feeds up until a week ago. Then, she started waking at odd times, often 45 minutes after her feeds. The last three nights have been really bad, and I noticed she was only taking one side during each feed so I tried to drop one of the night feeds. She didn't seem overly hungry last night, and had no problem waiting until 7 for her feed today. Last night, here is what happened (as far as I can remember).
E-6:45
S-7:00
NW-7:45
NW-8:30
NW-9:15
NW-10:30, dozing off/on until 11:15
E-2:15
NW3:15
NW- 4:30
NW-5:15
NW-6:00
Wake for day 6:55
E-7:05
She does have reflux, but as far as I know, it is under control. when she wakes, we usually just go in and put in her paci, and she goes right back to sleep. Any help would be appreciated, I am a substitute teacher and dredding the day I have to go to school after a night like last night!
