Coconut oil too strong for me ? Oil pulling & worsening of symptoms

I have been using cold pressed coconut oil for oil pulling for 2 months starting from once a day to twice a day in the morning and night time.

The first 2 weeks went well and I didn't have any noticeable reactions. And the tough time started right after the second week. I am not sure if that's the detox reactions or if coconut oil is too strong for me.

I am a bit over weight,suffering from acid reflux for 3 years and that's the major incentive for oil pulling.

And here's the worsening symptoms right after the first 2 weeks and it's been a month.
-bloating
I can feel there's a huge amount of gas in my stomach almost everyday and it is something that is not so common to me previously even I have acid reflux and things get worse especially when i am sitting on the sofa, or in bed.I could hardly sleep well.

-acid reflux & heart burn
heart burn comes all the time which makes me really frustrated.I understand that heart burn is possibly related to acid reflux yet sometimes I feel like a heart attack which makes me worried a lot. I went to the doctor several times, done the cardiogram and the doctor said there's nothing wrong with the function of my heart.

I didn't stop oil pulling even the symptoms is kind of unbearable as I am hoping that's the detox.And now I have just switched to sesame oil and trying see if things get better.
