I checked my wife's fingernails...and they do not look bluish in color ..

But to give an update ..doc(endo) said that take Iron tablets..which one ..or how much he said we will have to try what suits her.
Anyway , I read about proferrin ...their site says its heme Iron which is easily absorbed by the body and much better than normal Iron pills as it is easy on the stomach ( so no or less constipation)..Doc did not know about this ..but I am thinking will give it a try anyways...
b12 will continue as it is .....2000mcg/per day along with B2(100mg),B6(100mg),folic acid(400) and yes melatonin (will start taking that this week )
so will see how fast the recovery will be.....
