Hi Grace,
Between my government disability (Social Security) and the disability from my employer all my ostomy supplies are covered. I have a co-payment on the Rx drugs - I pay US$10.00 per Rx for generic, US$25.00 for name brand. All but one of my meds is generic. The co-pays add up to US$70.oo-US$90.00 per month. My medical is completely covered. Thank goodness for that as I know the full price for Rx and supplies is far greater. I really do understand about being so thin and not finding clothing. I am a size 2-4 petite and anything smaller is very difficult to find. I have had to buy clothes from the "girls" dept. When I was at one of the lowest weights I had someone say, "I wish I had the same problem." I realized they didn't understand the severity of the situation but I was speechless.
Regarding the Gatorade...you could try googling it to get more info about availability and use. It is available here at gas stations, supermarkets and wherever drinks are sold in many flavors. The cost is about US$1.00 per quart (946 ml). Just under US$2.00 for a bottle double that size. Please let me know what you find out from your stoma nurse and Dr. I'm hoping something is available to you "over-the-counter" (w/out Rx or hospitalization). Gatorade is also available in powder packets to be mixed with water and has the same electrolytes in it. Each packet makes 946 ml and costs a bit less than premixed bottled. I keep a number of these packets on hand in case I run out of bottled. I take Gatorade with me wherever I go. So far, it has been the only thing that has kept me from being hospitalized for dehydration (again)...I learned that the hard way!! I need to drink ALOT of it! I would be willing to mail you some of the packets to try if you can't find something there.
As far as being underweight...I felt horrible and weak...still do sometimes. Hang in there and keep trying. Gaining even a little weight can spark an appetite although as you know it is easier said than done. Keeping you in my thoughts and prayers!
