Hi, Pat.
If you are taking flax oil with yoghurt, you must strain the yoghurt
through cheese cloth or some other fine fabric in order to get it to
a cottage cheese-like consistency. Otherwise, the proportions will
not be right.
Ten tablespoons may be too much. But who told you "too much flax oil"
can cause depression? There have been so very many things of all
kinds said about what flax oil can do.
Also, are you eating fresh-ground flax seed? That needs to be part of
the diet, and probably should take the place of some of the flax oil
you are eating.
About depression, I do not think depression just "happens." I think,
in the majority of cases, there needs to be some
emotional/psychological reason for depression to occur.
