What is most popular and highly recommended amongst our clients/users is the  CBD2HEAL PURE CBD OIL 1000mg https://cbdmagic.ca/shop/cbd2heal-pure-cbd-tincture-1000mg-30-ml-bottle/ .  Some of our clients with severe  anxiety issues  are using a higher concentration ( 3000mg to 4000mg  bottle ). You will need to gauge  it for yourself because everyone's body is different and severity of the issue is different. I currently suffer from PTSD/anxiety and pain due to a car accident. I am currently using  the CBD2heal pure CBD oil 1000mg  at 1/2 dropper a day before bed. I noticed for myself that the 1/4 drop wasn't  helping enough until I increased the dosage. Now it's personally helping me relax, which results in a better sleep and also helping reliving my back pain. When you are testing out the dosage I would use the same dosage for about 5 days before changing the dosage amount. If you have any further questions or concerns please let us know.
