Is nausea a symptom of too much T3?

I recently had my thyroid meds switched to 100mg Tirosint and 20mg Cytomel. It's not helping clear my brain fog as I was hoping, but I feel very tired and nauseated and a little warmer after lunch and at night. My cortisol is low in the morning and higher at night, so I don't know if this has something to do with that or if I'm just on too much T3. My FT3 was 4.0 at my last labs, but I still had major hypo symptoms so my doc thought I may need to raise that level a little. I still feel foggy and dizzy like before so it hasn't helped me feel better. I just started taking 5mg HC in the morning, but since it has a short life, it should be out of my system by afternoon right? I don't have heart palps or a higher temp, just mostly feel really nauseated and tired and lights bother my eyes more.

I don't have the labs in front of me, but I think the range for FT3 was 2.4-4.2.  I just can't continue to be nauseous. I'm at work and the bright lights and my computer screen are making me want to throw up.

Yes, I changed the Tirosint and Cytomel at the same time. She lowered the Tirosint in order to increase the Cytomel.

It's not unusual to have adverse effects when changing medication or dosage.  Did you change/increase both the Tirosint and Cytomel, at the same time?  How much of an increase did you get?  

What's the reference range for the FT3? That varies lab to lab so must always be posted with labs.

Even with an increase in T3 med, it's unlikely that symptoms will be alleviated immediately.

Adrenal issues should be addressed before thyroid, so you may have to back off on the thyroid med until you get the adrenal issue under control. The nausea could be, either, the additional T3 med or the HC.  Side effects often go away once the body gets used to the medication.
