Propranolol withdrawl from small dose of 10 mg per day taken for short period of 7 days

I had typhoid around 2 weeks back with some full-head headache (continued for 5 days). So, I guess my doctor prescribed 10mg propranolol per day for the headaches.

I discontinued the tabs after around just 6-7 days on it mostly because of low libido and reading what it does to your brain and heart in the long run.

But now I'm experiencing withdrawl symptoms. I was 2 days off of my regular dose. Then couldn't handle symptoms. Had a tab. Again 2 days off of it.

My question is how long will they persist for such a short dose and short period of intake?

[Background: I'm a very healthy and fit person, 22 years of age. Didn't take even a single medicine for an entire year before this. I had no anxiety or migraine disorder or any heart related problem and I'm always a happy and in good mood.]

Any help will be highly appreciated.
