I think you need to take more than 1/4 grain. I would take a second 1/4 grain dose 8-12 hours after the first. Most people on NDT are comfortable with TSH <1.0 and FT3 >5.5.
Your B12 is very low. PA Society recommend 1,000 as optimal. Supplement 5,000mcg methylcobalamin for 3 months and then reduce to a 1,000mcg daily maintenance dose. Take a B Complex vitamin to keep the other B vits balanced. Folate is fine.
