Eddie, if the doctor looked up Naltrexone 50 mg plus, a day, for alcohol and drug addiction, I would say they take that in the morning. It is not the same as Low Dose Naltrexone. He might have made that mistake in time that way.
LDN has a different purpose, it works at night.
If I take it too early, and don't get to bed, I get a sick tummy feeling, like I should be sleeping to get rid of that feeling.
Good luck Eddie with you LDN.
