Hello everyone i am 26yr old/f and i have been struggling with weight problems for bout 5yrs now and i took xenical back in 2003 and went from 226 to 170 with all the worst side effects and this time around i m 222 and aiming to lose weight now that i have been diagnosed with high bp and i have a spinal disease (from car accident) So i need to lose the weight but i am not exp the side effects like before i have not been to the bathroom at all just a few simple headaches. Is there a possible way that it may not be working this time for me? any advice would b helpful thank you
