hi guys
does anyone get very eepy after taking 2nd gen antihistamines?
whenever i take them i sleep for 18 hours straight and feel disoriented for the next 3 days.
they also give me headaches
i thought that they werent supposed to cause drowsiness bc they dont cross the blood brain barrier like 1st gens do.

probably your body trying to recover after your immune system calms down. start stacking supplements

I would consider taking a different antihistamine, perhaps one that didn't have a construction paper label with a single word typed on it.

The 2nd generation antihistamines are all subtly different. Which one did you try?
All of them cross BBB in a significant capacity other than fexofenadine.
Other than loratadine, they're all antagonists at the H1 receptor (silent? unsure). Loratadine is an inverse agonist (diphenhydramine as well but it's first generation) which in theory means it should have subtly different effects especially at the brain.
tl;dr try fexofenadine
