I had that too. Eat more fish! At least twice a week. Even if you hate fish, you will love how it kicks those cravings. I tried Omega 3, and it helps, but not enough. For canned tuna, check the label for a claim "High in omega-3" as many brands have had their natural oil reduced during canning. Other oily fish varieties include small fish such as anchovies, sardines, herring and kippers as well as larger types like ocean tuna, Atlantic salmon, Spanish various mackerels, eel, trout, silver warehou, mullet, trevally, sand whiting and snapper.
