I would ask your doctor how often you can take it safely.It has a fairly long half life so it takes awhile to get out of your system but how that effects addiciton, I dunno.Have you had substance abuse problems in the past? If you had to go to rehab for other substances you probably have a different potential for addiction than someone who doesn't generally have addiction problems.Do you want to take it more often because you have symptoms more than a couple of times a month and it make you feel normal or do you want to take it as often as you can because you like it and you miss it when you haven't taken it? The second would be worrisome.
