"i was taking 3-4 lortab&#039;s a day 7.5 for 2 years for chronic low back pain. my new doctor won&#039;t write narcotics for chronic pain, so he gave me ultram 25mg. i was worried about withdrawal from lortab, but i had none, zero, i don&#039;t know how i just didn&#039;t because i have run out in the past and had withdrawals. i like ultram. i take it less than the lortab and it works just as well. i think lortab &quot;made&quot; my body hurt so i would take more of it (if that makes sense). i need 50mg sometimes 100mg to get relief and i can not take ultram er. if you are taking that, that may be why you are having dizzy spells ... it made my vertigo crazy!"
