Questions & Suggestions, Please :)

1) Can I ever chug water like I did prior to the sleeve?

• In the next upcoming weeks, I will be beginning my fitness routine. Before the surgery, I would chug water when feeling hot and dehydrated during my workout, drinking 30-50 ounces while at the gym alone. I'm assuming chugging only 5-6 weeks out probably wouldn't be a good idea, huh? Will I ever be able to do so cause I hate sipping with a passion, watching everyone else just chug away.
  

2) I LOVED icees/slurpees, especially Coca-Cola prior to my surgery. I can no longer have that due to carbonation. Is Fanta Cherry or Fanta Blueberry okay to drink? I tried searching to see if they are carbonated but couldn't find a thing. Additionally, I tried going to the icee website and my computer told me the site would harm my computer. Therefore, I'm turning to my VST community for help.

• The reason why I ask this is because this girl is going on a date really soon-- first time in ages in the upcoming week. I'm trying to avoid the dinner part since I'm barely eating. Thursday will be four weeks post-op and I'm still eating soup, with the occasional 3-4 bites of mashed potatoes or refried beans. I just feel dinner would be extremely awkward so I'm trying to push a movie. While I LOVE movie theater popcorn, I know it's too soon to have it. What about the fanta cherry or blueberry icee? If not, this guy is going to think I'm crazy for a thick girl like myself to not eat or drink anything (except water). Any suggestions? And yes, I went to this theater last weekend and they check purses on the way in so I can't take a drink of my own. I am tempted to wrap it in my hoodie but would feel extremely embarrassed if caught on the first date. What to do!?!?!
