Ok, that explains why you are struggling. Do you have anyone with you that helps you take care of yourself? If not, please try to get a friend or relative to pop in at least 2 times a day to help you. During recovery, when your body isnt getting enough calories and fluids, you can quickly tire and feel exhausted just getting up and down to use the bathroom. Are you able to talk so you can call your doctor? If you can, call and get the doctor to write you a prescription (tell them you need at least 2 bags of IV) to go to the hospital and get hydrated. After 2 or 3 bags of fluids you will feel so much better!
Try picking up some of that ensure juice. I get the blueberry/pomegranate which isnt too acidic and has a surprisingly good flavor. Most pharmacies or grocery store carry this.
Ensure juice PS... Im sending you a private message (PM). Look towards the top for a tiny flashing envelope to click on to get your message.
