I have recently had to replace chocolate and sweets with fruit as I was eating far too much of them. I have felt a bit better since doing that as I replacing artificial bad sugars with good sugars found in fruit.
I don't really add much salt to anything anymore as I generally tend to use herbs and spices instead to add flavour. A small pinch of salt generally tends to do in order to enhance and release flavour. There are plenty of herbs and spices you can use instead of lots of salt to give something flavour and to wean you off the salt:
e.g. for tomato based stuff i.e. sauces for chicken or pasta and pizzas: basil, coriander, parsley, oregano, italian seasoning, rosemary and/or cinnamon. Mix and match any of these to siut you or have just one type in the mix. My advice would be if you are to use cinnamon, don't mix with anything else as it's not that nice if you do.
For fish (if you like it), use parsley or dill to add flavour to a baked fish (bake it with the fish covered in foil) or mix it into a white sauce or a cheese sauce.
For curries, add some extra herbs and spices if the flavour isn't sufficient for you such as cardamom pods (remove before you eat the curry otherwise if you eat one it will blow your head off!!), star anise (like with cardamom pods, remove before eating the curry), fennel seeds, caraway seeds, turmeric, chillies or chilli powder, garam masala, bay leaves (remove before eating the curry), galangal (usually for Thai curries), kaffir lime leaves (again usually for Thai curries, however these can deliver a lot of flavour), ginger, cumin, asafoetida etc. This is just to name quite a few. I swear by my herbs and spices and have a cupboard filled with them and you don't have to be the greatest cook in the world either. Again you can mix and match these to find a combination that suits you.
Do a little research on the types of herbs and spices and what you can do with them as you may find something that you really like and forget why you ever needed so much salt in the first place.
