"I have chronic nausea and constipation. Will this help me"
You don’t mention if you have an underlying condition that is associated with your symptoms. Generally, it is the THC component of the cannabis plant that is associated with nausea relief, not the CBD component. You can read Dr. Frye’s answer to a patient question regarding using cannabis to prevent/relieve nausea here: https://www.hellomd.com/answers/572ce986213cd9000800004c/i-get-migraines-and-i-am-really-sensitive-to-light-to-the-point-of-nausea
I can also suggest this article: https://www.hellomd.com/health-wellness/the-next-step-for-nausea-treatment-medical-marijuana
that looks at the role of medical cannabis in treating nausea.
Finally, with regards to constipation, there can be a variety of reasons for this, such as dehydration, lack of fiber and exercise, or opioid use. You can read more here: https://www.hellomd.com/answers/58486699b3e43c000c5788fc/i-have-chronic-constipation-what-can-i-use-for-this
