Hello from JustAnswer. This is Dr. Love and I will be assisting you today.
It is common for someone with gallbladder disease to feel weak, sleepy, and bloated. These symptoms are not unique to gallbladder disease. The weakness and sleepiness are non-specific responses to any significant infection, while bloating is common with a variety of abdominal infections. So, it would be difficult to diagnose gallbladder disease based solely on these symptoms, but with the recent severe pain that was found to be due to gallbladder disease, it is reasonable to consider that these symptoms are due to the gallbladder disease.
The extent and severity of symptoms associated with gallbladder disease can vary widely. Some people can feel far more sick, and may be so severely ill that it is necessary to be admitted to the hospital for IV antibiotic. For someone with less severe symptoms, including those in whom the acute pin has somewhat subsided, and being treated with oral antibiotics, it would be common for some of the symptoms to still be present two days later, and that can include weakness, sleepiness, and bloating.
It may take several days for oral antibiotics to make a significant reduction in symptoms, and it commonly may take a week or so for the symptoms to resolve more completely. Some people may have some persistent nagging pain that persists until the patient undergoes surgery.
If I can provide any additional information, please let me know.
