Question about second fill

I had my second fill today. My first one on 10/30/07 was 3.5cc but 1.5cc was absorbed and I didn't feel any restriction really and have been doing it on pure willpower. So over the past 2 weeks I've only lost about 4lbs (don't get me wrong...I'm happy with ANY loss). Today for my second fill he took out the 2cc that was left in my band and put in 5cc omnipaque and then had me take a couple of sips of water. The water felt stuck after 2 sips. I've never been stuck yet but it felt like the water was sitting above the band and not moving and I had pain in my chest. I felt like I could literally just bend over, open my mouth and the water would pour back out. So he took 1cc out and I did a barium swallow and that seemed to go through pretty easy. So now I'm at 4cc and I'm wondering if I should have just let him leave the 5cc in there. I'm on mushies for 2 days and tonight I was able to eat 1/2 cup of mashed potatoes with no problems. Everybody else seems to do just fine with way more in their band. I'm going to be disappointed if I don't feel restriction with the 4cc.

Anyway I guess my question is this: Is it "normal" to feel stuck when swallowing water when you only have 5cc in your band? Or is there a chance I was feeling something else and it wasn't stuck? Having never been stuck I don't know what it feels like but it really felt like the water wasn't going through.
