No need to stop it. Go to the website
https://www.lipitor.com/patients/lipitorforyou.aspx and sign up for the Lipitor for you. For people with no insurance you would only pay $4.00 . They also have a generic version but if you can get the brand I would stick with the brand. You can also call them at 1-866-706-2400 as they have other programs that you may be eligible for.
Also call the company that laid you off speak to the health benefit department. You cannot just be cut from medical benefits, they would have to give you cobra for at least l8 months. I am not familiar with the pricings but ask your company.
