my sis was snorting about 800 milligrams of that shit a day. she's now been completely clean for a full year, but she went through some massive physical withdrawal. all heroiny like. it was not pleasant to watch. i couldn't imagine what it would be like to go through. just be safe. you know.
i wasn't aware about all that yoga info. i did a lot of it while i was pregnant and my instructor was really lax when it came to the poses cause we, ya know, were huge

she did make sure that we weren't in a position that would be harmful, but she gave us variations on the poses and we could pick what was most comfortable for us. i did really well for being as big as i was. she even had me in an inversion during one class. i was 8.5 months pregnant!
i think the biggest thing that she taught me that i still use is how to breath correctly. belly breathing. babies do it. it's very relaxing and seems a whole heck of a lot more efficient. i used it during labor until i just couldn't any more, along with cow/cats that eased the back labor i was having.
i also love tadasana (sp). it's great to do when you're standing in a long line and not moving. it aligns everything and eases the back pain that i have from carrying around an almost 20 pound sack of pure silly.
