A member asked:
Been taking 175mg of benadryl (diphenhydramine) every 4 hours yesterday i felt like i was overdosing how long till it's all out of my body?

Definitely overdosing: please call poison control center in your area, meanwhile don't take anymore benadryl (diphenhydramine) or any other antihistaminic, if drowsy or any abnormal symptom go to ER, with normal dosing it clears in less than a day, not sure how long with such high dose
