How much propranolol (base on mg) can cause an adult (young) guy to lose his balance and fall over (considering he takes citalopram 20 every day)?

Postural or after?: Medication response is very individual. If you notice you're feeling light headed upon arising from bed or after lying down a while, this might be addressed by simply waiting a bit before leaping out of bed in the morning. Fluid intake can help. If you're a little dehydrated, the propranolol effect can be magnified. you could discuss splitting the pill to only take 5mg 1-2 times a day.
