d want to start a whole lot lower. 1.5
grains is a significant drop in T4, from
150 mcg to about 56 mcg. But, you are also adding in about 14 mcg of T3. So, overall, adjusting for the higher potency of T3, you are still low of the 150 mcg T4 you've been taking. That being said, T3 can take a little getting used to, so if you get a T3 "rush" after taking your meds, you might ask your doctor about cutting back briefly (to say 0.75 gr in the am and 0.37 gr in the pm).
