Hello,
Thank you for asking at HCM.
I went through your history and would like to make suggestions for you as follows:
1. As per my experience, it usually takes 24-48 hours to feel good after coming off hospitalization. However, complete recovery of health may take upto 1-2 weeks.
2. Also, there are some anti-allergic drugs (antihistamines) that cause sedation,
drowsiness, as side effects. So they will also contribute to feeling lethargic and sleepy.
3. I would also suggest you adequate rest and light diet and plenty of fluids during day that will help early recovery.
Hope above suggestions will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish you the best of the health and a very good recovery ahead.
Thank you & Regards.
