new stage 4 with mets to liver

Hey everyone I am pretty new to the site, but have been reading yaws post since the early April. I am a 37 year old male with stage 4 EC and mets to the liver. To begin my story, in the late spring I started having pains in my chest around the sternum area. I figured it must be indigestian, so I blew it off for about a week and it got better. Well later on around June or July it came back, I figured i must be eaten to much hot foods and drinking to much beer on the weekends, and was maybe getting an ulcer. So I slowed lifestyle down a little and after a few weeks got better. After a couple of weeks it came back to the same place in my chest only hurting more and when I would swallow food and fluids of any kind or sometimes just swallowing my own spit. Did not seem to be getting any better so I decided to go to the doctor. This is now sometime in the middle of August the doc decided to treat me for ulcers. First we tried prilosic, then nexium, and this went on until the middle of December. Then he decided I needed to see a GI for an endoscopy. I had my endoscopy 1st week of January (easy), after the drugs wore off he talked to me and my wife, and told us I had a real nasty ulcer, high displesia, and a small hiatel hernia, and barrets. He also told us he had biopsied the ulcer and esophagus in a couple of spots, and would be getting back to us in a couple of weeks with the results, and to watch what I eat and drink until then. So my wife and I left not even thinking of cancer. On Mon. Jan.17th the GI called me at work and told me I had stomach cancer (devastating), so I had a cat scan on Wed. and met my oncologist on Thur. at the Derrick L. Davis Cancer Center in Winston-Salem, NC. He told me it definately looked like cancer, but wanted a pet scan to be sure. I had a pet on the next Wed. and met back with the oncologist(Dr.Thomas) on Thur. He told me it was stage 4 EC with mets to the liver(shocker). He told us how he wanted to treat it, also told us about trial options at other places, and told us if we wanted to get a 2nd opinion he could recomend several other doctors. He give us the weekend to think about it. However my wife and I did not know nothing about cancer and we both got a christian vibe off of Dr. Thomas so we decided to go with his treatment plan. On the 1st Mon. in Feb. I had a port put in the right side of my chest. On Tues. I started my chemo consisting of Taxatore, Cisplatin, and 5 days of 5FU with a constant drip. With 21 day rest periods in between, I repeated this 2 more times. Had another pet scan good news the tumors have shrunk. I then met with a surgeon(Dr.Stuart) and with a thoracic surgeon(Dr.Duncan). They told me the next step would be a trans-hiatel-esophagogectomy(thats the cut in the left side of my neck and a larger cut from my sternum to pass my belly button). They felt with my age and my good health this would be my best option, they then told me all the risks. I handled my 3 rounds of chemo like a champ the dr told me to eat what ever I want so I did. I weighed 246 before 3 rounds of chemo 266 before the surgery that I decided to have. Surgery was the morning of April 19th, lasted about 3 and half hours they took 20% of my stomach and 80% of my esophagus, removed the spot off my liver and removed 13 lympnodes the cancer in the liver and 1 of my lympnodes came back positive. On May 23rd(today) I started what I am calling cleanup chemo. It will be 3 rounds consisting of the same meds as the 1st with 21 days in between each treatment. I have already have my feeding tube removed before I found out about the cleanup chemo which I never had to use. I am however concerned about losing more weight now down to 229 pounds post surgery since I had surgery I cannot eat or drink like I did before which I knew would happen. Any advice?
