hi
i have had many good effects from doing qi gong
effects such as weight control, better sleep, not getting sick, changes in food tastes, changes in amount that can be eaten in one sitting, less salt .....
when you do your exercises, try to do them correctly, i started with some motion qi gong and quiet qi gong taught at my school, now i do the spring forest qi gong
just,"do your exercises every day," our master here would say, and so seems master chunyi lin
you will get results but it may take some time, take it as it comes, try to feel your energy flow
have fun and enjoy doing it, move your energy!
hope you keep going
