Advil is a product name - for Ibuprofen. Ibuprofen is available 'over the counter' at any UK chemist.
No, I've been taking it for a few years and I haven't gained any weight from it.
Yes, I've been prescribed singular for over a year now and have had to take double or triple doses of Advil PM as a sleep aid this year. Never encountered any problems. As these two drugs do not potentiate eachother, you won't all of a sudden feel stron effects or anything of that sort. Just be careful to avoid taking large amounts of advil.

You should always consult a doctor for such questions. But generally speaking you can. Advil's active ingredient is ibuprofen, which is an anti-inflamatory agent. Amoxicillin in a common antibiotic (think it is a derivative of peniccillin). I doubt there will be any interaction between these two.
Yes, it is safe to take these 2 prescription drugs without any interactions. Sources: Medical Doctor
I highly don't recommend it because if you keep taking unnecessary Advil or any other paid med. you will develop an ulcer.
