Sometimes sincere but over-zealous Christians go much too far by burdening people with restrictions that are not found anywhere in Scripture.
Scripture says that "There is therefore now NO CONDEMNATION for those who are in Christ Jesus. For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and death." (Romans 8:1-2).
It also says, "Do not be deceived, my beloved brothers. EVERY GOOD GIFT and every perfect gift is from above, coming down from the Father of lights..." (James 1:17).
Scripture absolutely does not forbid people from using medicine.
Please be at peace and know that Jesus truly loves you no matter what you choose.
I pray that you have a deep and restful sleep.
