I use Tramadol when needed and find it effective without making me loopy. I can't take anything stronger because it just makes me really tired. I find that I need to take 2 tramadol (100mg total) for it to really help with the pain. Can you try a higher dosage of Tramadol and see if it helps? There would be no way I could take a Lortab and pay attention to anything, I get so drowsy on those things! Plus, I find hydrocodone or oxycodone to be very constipating, which just makes my stomach feel worse.
Love my heating pad too, but it is starting to leave a rash on my stomach.
