Long story short - I'm exhausted.
I've been taking 40mg of propranolol for heart palpitations and it's been working a treat. However, ever since I've been taking it I've barely slept. Out of desperation, I bought some herbal sleeping tablets (Hops, Valerian, Passion flower) but the leaflet says to avoid taking them with beta blockers.
I can't find anything online that explains why or what the effect would be. Would it really be so bad?
