Awesome post! Here's my own flu receipt (I was sick 1 week ago, and I skipped school for 5 days... Yuck...)
These things that you've taken from the pharmacy are OK, but here are my advice:
TylolHot- substitution to Fervex, but it has lemon-ish taste, and it contains more Paracetamol (it drops your temperature faster)
Стрепсилс: Мед и Лимон- It's the weakest from the Strepsils, and it didn't helped me. If you prefer Strepsils- you can buy the blue one (I forgot the flavour), but it's more minty and the sore throat is gone in no time. I usually prefer Нео Ангин/Neo Angin, but Strepsils is good anyway.
The tea- Биопрограма is OK, I've drank a lot of tea, and the best combination that I found was: Pickwick (Especially black tea- I'm sure you can find that kind in Billa, it's in nice black boxes with 20 little packets of tea inside) + Bee Honey + Lemon. I guarantee it's an awesome combination.

Get better soon!
Бързо оздравяване!

P.S. I hope I've helped!
