I wish I were there to give you a hug and reassure you that you'll be okay. I cannot take Vicadin, because it gave me rapid heart and I had painic attacks, ultram did this to me as well(though it didn't work at all for pain).
Are you eating enough? Taking your meds with at least a little food? Are you drinking tons of water? It's hard to do all of these things, I know, it sounds like your body is telling you it's missing something, or that the Vicadin an' Lesa ain't a good match?
Sorry so late answering, you could say I've got a few things going on right now...
Love and hugs from your pal,
Janet
