Lactose and Synthroid

I discovered that Synthroid has lactose in it and I'm not able to tolerate it. I get highly congested when I drink milk. So I did some research and found that Levoxyl does not have milk in it and switched drugs. The congestion is gone but I am much dizzier on this drug. It has been less than a week but considering the drugs should be bascially the same, it surprises me.

I thought I'd out this out there for lactose-intolerant folks like me so you know.
