Can benadryl still make you feel drowsy the next day? i took it at 5:45 last night and still feel weak and drowsy even though i s!ept.

Yes indeed: Diphenhydramine (Benadryl®) can be an effective sleep aid, but is long acting and often has exactly these effects. Aas you probably know, all sleep aids are discouraged unless really needed. Avoid alcohol near bedtime (causes rebound awakening in the middle of night or early morning hours). If sleep aid needed, a shorter acting one by prescription is recommended (e.g zolpidem, i.e. Ambien®).
