I would add sunglasses, soft ear plugs...at times noise sensitivity was a problem for me. If you feel like you cannot swallow pills ask for pudding. It is easier to swallow pills with pudding than water. Comfortable traveling clothes and shoes. Do not take any shirts that have to be pulled over your head or tight around the neck, they may cause discomfort. If you are a lady do not be surprised if a bra is uncomfortable or even cause shoulder and or neck pain. Try sport bras, or even cami's or undershirts.
While I know it sounds like a good idea to take your own meds it is not a good idea. As a nurse myself I know the any hospital will not let you take your own medications unless specifically written as an order by the doctor. We are responsible for everything that you take. What happens if the patient brings the wrong med, dose, expired, had a reaction etc? Just something to think on.
Glad it helps, we have other posts that have suggestions too, so please check. We are praying for you and have you in our thoughts. Please keep us posted and let us know how your doing.
Sending you a lot of hugs and prayers and well wishes!
