Welcome. Well done on 7 days and especially on vacation.
I think you'll find that going back to work clear headed and functioning a lot better will make it easier to stay focused. Change your routine when you come home after work, keep coming to SR reading and posting.
A lot of people, including myself, find it harder to resist when being at home.
Weekends, vacations, etc.
You've done well already.
English is not my first language either and it's never made any difference in the support I have received, so don't worry about that.
