I really don't know.... every other day for the B12 injections?
For how long... a week, 2 weeks, forever?

Are they cyanocobalamin? Some people can't handle them that often because of the cyanide in them.
Also if you are not converting to methyl active form, the cyano is useless.

Tumeric might cause nausea..if you don't take with enough water.

What dose of B complex is it? Many people find taking after breakfast is the best for this. It can upset the stomach.

The fish oil should be taken with food too.

Some people get heartburn from the old alpha lipoic acid... most of us here use the new R-lipoic stabilized, and that only needs 100mg a day. Much easier on the stomach. The old one is not absorbed well unless taken on an empty stomach.

I think you should discuss this with your doctor. Starting slowly one at a time, instead of all at once might demonstrate which things are bothering you.
