Dear patient
thanks for your health concerns. that is a lot of dyphenhydramine taken all at once; depending on the presentation of the separate tablets of dyphenhydramine (Benadryl) you could be ingesting from 176 to 226 mg of the medication... that is 4 or 5 times the dose we use for allergies or congestion. the main side effect is somnolence which is what you are trying to achieve but at those doses other such as urinary retention, confusion, etc could be seen. furthermore you are taking other agents with sedative properties and effects can be synergistic
truly yours
