i did when i first took it but have been on different ones to see which suits me best, i aksed the doc about the weight gain and he said if you take pills it will as it has to go through your liver but obviously the other sorts dont, i use gel at the moment and that seems to be the best so far, i did use the patches which were great for a while but then they started to make me itch, its just trial and error, suppose it depends on why you have them, some cos of age, some cos of surgery
