My midwife recommended that I take B-12 daily during a very nauseous first and second trimester of my second pregnancy. I took one a day and they really did help with my nausea and vomiting. I can't say that it completely went away but it did subdue it a little. The pills were easy to swallow and tasteless. I think vitamin B is also supposed to help you have more energy throughout the day. I did not experience this benefit, though maybe under normal circumstances I would have. Your baby is basically made up of cells which are constantly multiplying and dividing during those stages and forming a little human, so I can understand why I didn't feel any more energetic. I have used this brand for other vitamins too, such as Prenatal multi-vitamins and CoQ10. This brand always has coupons and is one of the greatest values at most super stores and pharmacies. I'm not sure the difference in quality between vitamins, but they have always worked well for me.
