I would give it a good couple weeks to adjust and get used to any medication you are just starting to take.
Your Mom has been on it for 25 years so she is well adjusted to it and you probly cant tell she is even on medication. give your body time darling, it has only been a day or two your body has to amp up and such..be patience .
I know how much ya want to be on the dock enjoying the outdoors and fun with family .It feels like your a prisioner in some ways because your can do that .but let yourself and body get used to the meds first then you can get out there again.
sending you healing thoughts and low low pain wishes to you.
Keep us posted on how things go Melissa .
PEACE
