In brief: Definitely

400 mg is the maximum daily dose for severe allergic reactions, in a hospital setting.
For sleep, 50 mg should be the maximum, to avoid both unpleasant and even potentially life-threatening adverse events. Central nervous system effects are particularly significant. Even for "benign" meds, packaging dose limits are not suggestions; they balance efficacy with safety and should be followed.

if anxious try reading on mindfulness to help you relax to sleep. Nothing replaces seeing your physician. Wishing you'all the best.

Thats a lot of Diphenhydramine can cause confusion, delirium, heart attack, impaired judgement performance for 72 hours or more or even death.
