Yeah you're sensitive to it.
That's great that you are so sensitive to these things.
Less is more 
When I had the flu a couple weeks ago, I had a >100 degree fever and could hardly lift a finger.
Complete body & soul fatigue.
I mixed a spoonful of White Vein Maeng Da into some Golden Milk (Turmeric, Coconut Oil, Almond Milk, Ginger, Black Pepper, Honey, etc).
Within an hour of drinking it I felt almost completely fine.
Seriously it was a miracle!
Also, after I got over the flu and body aches, I was left with a horrendous sore throat.
It was so bad that breathing & drinking water was agony...
So I tried a spoonful of Kratom again with Aspirin.
I was singing within the hour...
There's alot more to Kratom than just pain relief.
I'm curious to see more studies down on it.
I just have to respect it because I've struggled with drug addiction before and Kratom seems to be the perfect daily ally.
Although I feel that it (and other opiates) takes a piece of your soul...
