My God people! I am so happy that this many people replied and wished I am okay!!! I am smiling now... Yes I drank the whole bottle of syrup, and for a good measure took two betablockers, and well nothing happened, I slept for five hours in total (woke up just now.) So I think I may be on either very small doses or placebos....
But I want to thank personally each and every one of you for the support you've shown to me! That means a lot...
Edit : To avoid further confusion, I should add that I am on
betonin ast syrup and that it doesn't contain any betablockers despite its name. It contains alcohol.
