Sliders are soft or saucy as far as I know

It's difficult because you might even be having too few calories. I worked out my BMR at a stone heavier than I am now and I needed 1173 just to lay down all day and breathe/be alive. Do you see what I mean?
I think maybe try eating mainly protein and veg at meals, easy on the sauces etc and try and exercise a half hour daily and see what happens. It's such a long process sometimes and I know it's off putting. It will get better I promise.
Also, what is making you sick daily? Is there a certain thing you do/eat before or time that happens?
I think swapping chips (I know oven chips aren't too bad) with a small baked spud (dry no butter) might help you feel fuller if you can tolerate them.
I can't eat chips, most pasta and even rice causes problems but as I said my band is very full. I can normally eat any veg, mash in small portions, and things like chicken, tuna , ham, thin sliced beef etc...not chunky meat though..and not sausage as I found out in a horrible way not so long ago lol.
Have to try and work out what's making you sick though as that's not good for the band (so I read) xx
Just wanted to add this
Phase 5 – weeks 6 onwards
Normal diet - you are now ready to continue on your long term eating plan. At six weeks your first band fill is usually done and you will start to feel the restriction your band is making around the top of your stomach. Remember, you are not just eating small amounts to reduce your calorie intake and lose weight, but you are aiming for a healthy nutritious eating plan as well.
Six golden rules
Each individual differs in the foods they can eat, but there are six golden eating plan rules to follow if you are dedicated to obtaining the greatest benefit from your gastric band:
- Eat three meals per day – your new pouch at the top of your stomach empties slowly throughout the day and you should be satisfied eating three meals a day without getting hungry in between meals. Beware of developing 'grazing' eating patterns of small snacks throughout the day.
- Eat healthy, solid food – soft food slips down easily and whilst this has the benefit of being less likely to block your stoma, you will likely end up eating more over the course of the day. Many soft foods are also higher in fat or carbohydrates and as a consequence you may be taking more calories than you should and your weight loss will slow down or stop. Choose solid foods without lots of sauce (e.g. small meal of chicken and vegetables) and you will eat less overall and stay full for longer.
- Eat slowly and stop as soon as you feel full – most obese people are used to rushing their meals and as there is a time lag from stretching the wall of your stomach and telling your brain you are full, you need to be careful with this one or risk blockage, pain or vomiting. Take tiny bites (cut meat up to the size of a pencil-top rubber) and chew each piece 10–25 times. At some point you will start to feel a tightness in your chest. Stop eating and if you are hungry again a few minutes later, have a little more.
- Do not eat between meals – you should not need to eat between meals because of hunger if you are eating three sensible meals per day.
- Do not drink at meal times – Liquids speed up the passage of food through the stoma and ruin the beneficial effect of slow emptying of food from your new stomach pouch. If you have a drink immediately before your meal you may also find that your stomach is still full and you can't eat your meal. So avoid fluids half an hour before your meals, and for one hour afterwards.
- All drinks should be zero calories – As liquids do pass through your stoma so easily, calorie laden drinks, including alcohol, will simply add calories to your daily intake. Women need calcium, and this can be obtained from skimmed milk, but avoid juice, fizzy drinks (the gas can also cause considerable pain), squashes and milkshakes.
