As with many of you, I have experienced all of these symptoms. I generally have a breakfast drink smoothie in the a.m. Some mornings, even that doesn't go down too easily. I really don't do well at lunch, as I feel frustrated that anything healthy would be too difficult to attempt. So I often have milk and carbohydrate.
I start to get hungry by late afternoon, and snack sporadically.
Dinner goes down more easily with small sips of wine. Interestingly, I often have more success when eating out. I think it may be that I'm more relaxed . At home, I'm still working on bite #3 while everyone else is finished and ready to leave the table. Having said that, I went out with friends on the weekend, and was only able to eat a few bites of my dinner. I had to go to the washroom a couple of times to bring up lots of phlegm and my dinner. In spite of that, I continued to have that uncomfortable tightness in my chest, which I find quite distracting. I often need to belch to relieve the pressure.
The really interesting thing is that I have never had a fill. My surgeon's policy is to wait until 6 wks. post-op for the first fill. Since I was losing, he felt it was unnecessary. That was 2 yrs. ago. I did really well for the first 10 months, losing 75 lbs. Since then I'm sure that I have regained some (although I have never weighed myself), and I'm disheartened as I have about 100 left to lose.
