I think nostalgia is a big factor everyone faces and needs to watch out for.
I can honestly say that nostalgia bought me undone more than anything else - wanting that drinking experience to be exactly like I (mis) remembered it, and me wanting to be the drinker that I know now I can never be.
It's like that old girlfriend - she was bad news, but you still miss her, still grieve her passing a little, even romanticise some aspects about her - until enough time passes and you realise how good your life is without her in it.
You're doing well BSU. 7 weeks is great.
Give yourself time - and remember past all those rosy good memories - focus on why you quit - read your old posts if you need reminding
