Starting propranolol

I was wondering how some of you started propranolol. For reference I have eds, freshly diagnosed with POTS. In comparison to others I am fairly mild, but it’s still shitty. I got told to take 10mg per day. When talking to eds specialist regarding new medication - not propranolol specifically - she said I should start with a quarter of the normal starting dose and then slowly more. But 2,5mg and a quarter pill - not that easy to achieve. Thinking about 5mg. And yes I had quite bad experiences with new medications and I am really nervous about it 🫣🫣
