I am tired 47 hours after receiving general anesthesia. is that normal? (i've been tired since i've woken up with it).

Maybe: In general the medications given to you during general anesthesia . Have long ago worn off. However the stress of the surgery probably has not. As well you may be taking pain medications . I would think your tiredness is more attributable to the latter two factors.

Depends: Usually you do not stay tired that long after general anesthesia. It would depend on how long you had anesthetic, type of case, type of anesthesia, and on the person. Some people have rare metabolic defects that may keep you tired and or weak after an anesthetic. Talk to your anesthesiologist who did your case.

Possibly yes: Depending on the type or duration of the operation this can be completely normal. Anesthesia is not a normal sleep for a patient. Thus the sleep is not restful and the patient wakes up feeling tired. That combined with the physical damage from the surgery itself can cause sleepiness.
