When I first became Christian I would get demonic attacks while playing my (at the time) favorite game LoL.
I started researching more into the game and found it highly demonic.... Needless to say I do not play it today...
This leads me into something else though...
Not everything is demonic, not everything is Satan....
A lot of it is you, or I should say your flesh....
Imagine a heroin addict that is detoxing. The withdrawals, symptoms, side effects, cravings, etc. those are not necessarily from Satan... Now Satan can use those experiences to his advantage, but those experiences are from the flesh...
When you train your flesh to become attached to a very harmful yet addictive substance, the longer you were attached and the more harmful it is, the harder it is to tear away...
Now people like to quote ephesians 6 at times like this and say we do not war against the flesh and blood but against principalities...
I argue that they are jumping a step ahead to quickly...
Glatations 5:24
Now those who belong to Christ Jesus have crucified the flesh with its passions and desires.
Ephesians 4:22
that, in reference to your former manner of life, you lay aside the old self, which is being corrupted in accordance with the lusts of deceit,
Colotions 3:5
Therefore consider the members of your earthly body as dead to immorality, impurity, passion, evil desire, and greed, which amounts to idolatry.
So we can see with those verses your body is full of evil passions and will... This means your at war with your body, you have to fight it.... And you have to crucify the flesh with its passions and desires....
Notice, it does not talk about Satan, Demons, or others....
It talks about a person warring/battling with ones self in a fight to the death... Satan can influence this battle, but this battle started with you... and will end with you....
But just as Satan can influence, imagine how much God can influence... If a lowly creation can influence you, imagine how much the creator of everything including that creation can influence you...
This is the hardest battle you will ever fight in your life, and it is never ending...
Edit: never ending while we are here on this earth.... And we will have to fight it daily.
I will end with Christs words...
Luke 9:23-24
23 Then he said to them all: “Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me. 24 For whoever wants to save their life will lose it, but whoever loses their life for me will save it.
