I would like to add something to the discussion here. Jihad has rightly mentioned by you as not being 'war' because it basically means struggle for good. Any struggle for good is called Jihad and it includes self-control against bad or criminal traits of personality. Biggest jihad is the struggle against our ownselves; the evil part of our personalities.

However, the meditation and peace is brought by another Quranic concept called Dhikr. It translates to remembrance and means remembrance of God. Thats is what brings assurity. There are many forms of it. Here's the verse.

"Those who have believed and whose hearts are assured by the remembrance of Allah. Unquestionably, by the remembrance of Allah hearts are assured." (Quran, Chapter 13: Verse 28)

As far as wine or intoxicants are concerned, they are the exact opposites of Quranic meditation. So much so that remembrance of God is mentioned in the same verse as intoxicants or gambling. Here's the exact verse.

"Satan only wants to cause between you animosity and hatred through intoxicants and gambling and to avert you from the remembrance of Allah and from prayer. So will you not desist?" (Quran, Chapter 5: Verse 91)

I hope my comment has added to your knowledge, as well as brought value to this post.
