Well I am an addict and I can tell you chemicals seem more powerful than prayer. I prayed for 13 years for recovery and I did everything else I could do to escape, but the addiction kept catching up with me. Prayer wasn't effective because it couldn't remove the chemicals that the addiction lived on and secondly it couldn't replace the chemicals that my brain needed to keep my brain functioning normally. The only thing pray did was give me a temporary coping mechanism at times but after 13 years I just quit praying and did something about it.
Something a lot of people, especially non-christians as yourself don't realize is that God never said he will heal everybody of everything. What he does promise is that things will work our for good
for those who love Him. "Good" doesn't always mean "miraculously instantly healed". We (Christians) are certainly told we can (and even should) ask for it, but we are not told that every one of those requests will be answered in exactly the way we want it to be. God is not our robot. The apostle Paul himself had a physical affliction that he wished God would heal, but God never did. If God wouldn't do it for Paul, why would he be "required" to do it for anyone else. Many times God has reasons for these type of things that are well beyond our understanding so He doesn't explain Himself to us about it.
When Jesus healed people, He told them it was their faith in God that healed them. But most times God intends for us to use the resources He has made available to us, such as skilled doctors, proper use of drugs, resisting harmful use of substances, or whatever is appropriate for the situation. You have made it clear in posts elsewhere that you do not have faith in God so at this time I have to agree with you that prayer (faithless prayer) will certainly not be any more powerful than the chemicals within your body. Until and unless you come to have that faith in God, you are right, you need to rely on other methods for your healing, and I give you a ton of credit and respect for doing so and working to have success at that! Don't get me wrong, I know God CAN heal people, even to the point of making something (a harmful chemical in your body, for example) completely disappear into nothing. While that
seems impossible to a rational mind, I've personally witnessed it happen. But even for those with faith in God, He doesn't always do that. When He does do something like that, His reason and goal is to somehow bring glory to himself and to testify of His power to us. It's not really just about making a person feel better. So don't let yourself think that because your prayers didn't bring about an instant healing of your addictions that God doesn't have enough power to do that, or that He isn't real. It's just that God is our
God and we are intended to be His servants, not the other way around.
