At my urging, my husband tried a course of using LDN. I used a compounding pharmacy for a liquid Rx of 1 mg/ml so I could adjust dosage to 0.5 ml steps without pill splitting. I thought I saw minor improvement in brain fog at 2mg/ day. As I tried 2.5 mg/day for a week and started 3 mg, my husband started experiencing vivid dreams and hallucinations. I had split the dosages of 2.5 to 2 at lunch and 0.5 mg at dinner. As he started the side effects, I moved the total dose to all at lunch. The side effects so disturbed him that he chose to totally stop all of the LDN. [ I tried reducing the dose back to 2 mg at lunch which previously did not provoke dreams, but they did not totally cease even at that dose and timing]. Can anyone suggest any protocol where good effects might be obtained below 2 mg but without side effects?
