This sucks!

Okay my first week out of surgery sucked, barely got much fluid down, was only able to drink water, nothing else. I was nauseated my first week, The 4th day out I had to go to the ER, I was fine all day, but at night I got hit bad with nausea and went to the ER, they couldn't get the IV in so I told then I didn't want it cause it hurt too much. Then I went back in the waiting, nauseated like heck. So a few hours later they brought me to a room which I waited a couple hours to get bloodwork and I almost passed out and almost vomitted so they laid me down where my feet were up in the air it helped for awhile and I got up and the feeling came back. They did a fleet and it helped a little bit, when I got home, a few hours later I felt nauseated again, last I can remember it went away a little and came back on the Friday so I called my surgeron and he told me to see him, did a barium swallow and everything was fine and he gave me a better nausea med it made me better for 2 weeks then this Friday night i ate something all of a sudden I felt nauseated I took a pill and it never helped! So I've Been in bed since then, been up here and there but I then have to go back and lay down, it seems to be the only thing that helps. Okay so I'm thinking the nausea feeling isn't in my stomach, it's in my throat, I heard it's reflux, and I have a bad taste in my mouth, had that feeling since Saturday, it got so bad where it just happened, vomitted but nothing came up, and I feel like I got to still this sucks I didn't want to live like this I'm only 3weeks and 3days post op, but still! I wanna be out with my friends and this is preventing me to do so ): I'm losing hope and feeling like I made the biggest mistake ever, you all say it'll get better, what if it doesn't? If I ever get the band removed, would I still feel like this? I just want to be like myself again, this sucks!!
