I just found out today Since I started, my first bottle (30 pills) of Nal was by Sun Pharma, which was Nordict. After my first bottle up to today I have been using mallinckrodt manufacturer version. I dont know why, but it is not as effective for me.
As a Final Test (god I've possibly wasted 3 months Today on the wrong pill) I will be ordering Sun Pharma 10 Pills Nordict and from Intas Pharmaceuticals 10 Pills Naltima.
I have a feeling that whatever Nal I have from Mallinckrodt, it is not as effective.
Once I get these and test them out, I will report back to everyone.
EDIT: I just discovered that there are MANY different manufacturers. Here is a resource I will share on the main discussion forum for future since this is really bothering me to know I could be taking the wrong type for me..
