I used to have problems with dizziness. Giving up gluten and milk products help me, personally. Praying you will be guided to the cause & cure for your problem, hopefully in some natural ways with no side effects.
Father God in the name of Jesus I pray that your son will be healed and the dizziness would stop. I pray that he will not grow faint and weary and that his strength will be renewed. I pray and ask that you will give him your strength Lord and that his hope and trust will always remain with you in Jesus name I pray, amen.
