Your FT3 is good so I'm not sure how much benefit you will get out of adding T3 to Levothyroxine. You could however quarter a 25mcg tablet and add 6.25mcg to see whether symptoms improve.

I'm scare to increase my dose, it's already very high . I wanted to exchange T4 on T3, but still not sure how to do it properly . Please, maybe more people can share their experience with me.
People get very scared by taking thyroid meds, but if you are careful there is nothing to get scared about.
As Clutter said above you can switch 10mcg T3 for 25mcg T4.
If you divide your T3 tablets into four quarters (use a pill cutter or a scalpel or a hobby knife), a single quarter will only contain 6.25mcg T3 (assuming your pills are 25mcg pills), which is a very small dose. The worst that could happen with 6.25mcg is that your heart may be unused to T3 and may speed up a little bit. It should slow down again quite quickly, probably within an hour.
Your body will digest 6.25mcg and it will be out of your blood stream within about 6 - 8 hours. So even in the unlikely event you had a bad reaction to T3 it wouldn't last long. Bear in mind that being terrified of the T3 will make your heart speed up too! So please don't be anxious.
So, if you are determined to cut your level of T4 when you take T3, I would suggest :
a) Reduce your T4 dose down to 150mcg per day.
b) Take a quarter pill of T3 and take it first thing in the morning.
c) Take another quarter pill of T3 later in the afternoon.
Once the heart gets used to having T3, your heart may speed up when your body runs out of T3 and you are due another dose, as well as soon after taking it. This confuses people when they aren't used to it. But once you understand what is happening it becomes easier to understand the signals your body is giving you.
Don't be tempted to rush your increases in dose of T3, and don't rush to reduce your T4 either.
If at any time you are worried that you might be taking a little bit too much T3, then just don't take it for 24 - 48 hours hours, cut your overall T3 dose by quarter of a pill, and start taking it again with the lower dose.
I take now 175mcg of T4 in the mornings. Is it correct dose if I start from today on 150mcg T4 plus T3 quarter in the morning and another T3 on the afternoon?
