I do 60 mg times 2 per week also. No AI as I apparentely am a low aromatizer. My E runs steady at 15-16 confirmed by BW three months in a row. I also consider myself nip sensitive. I would think the sensitivity you experienced was just your body adapting to the new substances. Do you still have sensitivity?

I would consider eliminating the AI entirely or reducing it even more for a while and see what happens based on BW and how you feel. I know, its scary. You can always get some nolvadex on stand by if you think your levels will spike. It will allow your E to raise and eliminate any chest receptor issues. You will probably feel better in the 20's with your E level. I hope to raise mine somehow!
