i know how you feel with both things.  i am 22 and i have as many problems with my body as my mom and my grandma are having.  it is really kind of ironic to think that i can sit down and relate with every pain that my mom and grandma can feel.  i am really exhausted everyday as well and i know that a small part of it is the meds but so much of it is the rsd.  i have a horrible gate that in itself is tiring.  i have recently had a miscarriage then infections from the procedure to remove the fetis.  then had to over come two more infections.  i had a leep procedure done and my gall bladder removed just last month and there is still something going on with my stomach.  i get the same feeling of not wanting to eat because it hurts to eat.  i was wondering if you have seen a g.i. doctor yet to see if there is something that they can do.  do you get bad sharp pains in your back?  that is what was happening before i got my gall bladder removed.  you might want to consult with you doctor.  make a list of the pains that you get, kind of like a journal, for a couple days and take that to your doctor.  one thing with me is that i have some food allergies so my doctor and i are working together to make sure that that is not what is giving me the pains.  good luck with everything and if you have any more questions about things just let us know. with rsd family love.  blueyez2107
