Leslie,
I can certianly understand the hesitancy to go the surgical route, since it involves altering your body, risk of infection, and pain, and youve certianly had an ordeal already wiht the cancer. I'm glad that they found a med that helps somewhat with the being thirsty. Yes, I would talk to your GP about taking it during the day. If that turns out to not work long term, there are overactive bladder medications that are avaliable. They work for some folks, but not for others. Some drug names include Ditropan, Detrol, Vesiciare, Enablex, Topiaz(i think) and Myrbetriq. I have taken almost all of these, and they did not seem to help to the point of where i wanted them to, that is get out of diapers completly, but hten again, I don't have an overactive bladder..i have an underactive bladder..and its harder to treat with meds. Also, keep in mind that that they would reduce, not eliminate the number of accidents. You said that that the hospital got tired of changing your diaper every hour and a half. I'm guessing you are currently using a brand like Depend? I would suggest that should the meds not work, you consider upping your protection to a premium brief, such as Abena, Confidry, Seni Quatro, or A+, all of which are avaliable at
www.xpmedical.com. These diapers are more expensive, but you would actually save money because they don't require as many changes. With the amount of absorbency, they absorb what 4 regualar briefs would absorb. Also, another option to consider is something that I am trying myself with good resuts, which is adult size pocket diapers off this website:
http://wearing-adult-diapers-com.myshopify.com/ Don't let the price per diaper of 40 dollars scare you, you actually would save money over time since these are washable. I have reseasrched cloth quite thourugly, and these are the closest thing to the convinenence of disposables while still being reusable. The main thing to keep in mind with these pocket diaeprs is to wear enough inserts. 1 insert would last rougly an hour for someone whos wetting heavily.. so you would want at least 3 or 4 per diaper.
I hope this helps!
Peace out!
Rob
