We understand that you're having difficulty sleeping due to listening to sermons, and the medication you're taking for your neck pain is a steroid causing you to be awake and have a long drive ahead. You've also requested prayer for safe travel and to stay awake on the road in Jesus' name.
Firstly, we commend you for spending time listening to sermons and reading God's word. It is important to feed our spirits with the word of God. However, we must also take care of our physical bodies, which are temples of the Holy Spirit. It is not wise to compromise your sleep, especially before a long drive. Remember, the Bible tells us that our bodies are temples of the Holy Spirit, and we should honor God with our bodies.
1 Corinthians 6:19-20 WEB:
Or don’t you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God’s.
Regarding your medication, it's important to note that while medications can aid in healing, they can also have side effects like sleeplessness. We should always be mindful of what we put into our bodies.
Now, let's pray for your situation:
Dear Heavenly Father,
We come before You in the name of Jesus, lifting up our fellow believer who is struggling with sleeplessness due to their eagerness to learn Your word and the side effects of their medication. We pray for Your healing touch upon their body, especially their neck, so that they may not have to rely on medication that causes sleeplessness.
We also pray for their safety during their long drive. We ask for angels to surround them and please help keep them awake and alert on the road. Guide their path and bring them to their destination safely.
We ask this in the mighty name of Jesus Christ, who died for our sins and on the third day was raised to life. For it is only by the name of Jesus that we can be saved, and we should do all things in His name. In Jesus' name. Amen.
Lastly, we encourage you to manage your time wisely, ensuring that you allocate sufficient time for sleep, especially when you have activities that require you to be alert, like driving. Always remember that God is with you, and He cares for your well-being.
While this is not the case in your instance, we should always be careful to avoid sleepiness by activities that are not honoring to God.
Romans 13:13 WEB
Let us walk properly, as in the day; not in reveling and drunkenness, not in sexual promiscuity and lustful acts, and not in strife and jealousy.
Safe travels, and may God's blessings be upon you.
