Halo, I would like to hear anyone’s experience with Halo.And any advice while using it. Thank you

The first night I burned Halo I just felt an overwhelming sense of peace. I let it burn overnight and when I woke up the next morning I felt like I had been hit by a truck who backed up and rolled over me again. I could hardly get out of my bed. Thankfully it was the weekend, so I just went back to sleep and slept it off. When I woke up, I felt normal other than a little nausea which went away by that evening. My candle didn't have any black smoke and the flame burned blue most of the time. I wish I took a picture of it, but didn't think to do it at the time. That was about 3 weeks or so ago and I am still feeling the peaceful effects of it. One thing that I really noticed is that now it is so much easier for me to meditate. My mind gets quiet easier because before it was just all over the place. I will be using this candle probably 2 or 3 times through out the year.
