Some studies show that 150mg of naltrexone are safe and more effective than 50mg. Any thoughts on this?

In the past I went to 75mg because the nal seemed to lose its effect (for me) at just 50. I'm restarting the process so may end up there again. I remember reading somewhere that potential liver issues don't kick in until much higher doses.

I've been doing some research on use with eating disorders and know of at least one person taking 150mg daily, doesn't seem to be bothering them and helps with cravings for junk food/binging. I'm not too keen on going to that level myself, so going to try tackle those issues a different way.
