Earlier quoted context omitted.
Jus fyi but the "non drowsy" antihistamines are fundamentally different or anything, they're just the same type of drowsy antihistamine but with the dose lowered so it barely works unless you take more than one, thereby making it drowsy again
This is incorrect enough as to be dangerous (IMPE, I am not a doctor). They are non-drowsy because they do not cross the blood brain barrier effectively as I understand. Second and third generation antihistamines are fantastic.
I must be overly sensitive or have a deficient BBB because 10 mg loratadine transform me into a lethargic zombie for about 48 hours while providing minimal relief. A double dose of vyvaanse and a few coffees are not enough to bring me out of that state.
