I’m just getting started really. I started at 1.5 mg capsule for one week at bedtime. Then increased to 3 mg at bedtime for one week. Then reach the final dose of 4.5 and have continued that at bedtime. I think it is helping with my pain. It may be too early to tell, but I think I noticed a slight difference. I’m taking it to try and calm my anxiety and several other issues. I get it through my functional doctor. Have not had problems with insomnia. Doctor said if it did cause insomnia just take it in the morning but I am not a doctor and this is not medical advice .
