When I did RTM I don't remember there being any limits at all on quantity - you had to make your own judgements, which was not easy after the regulation of abstinence but part of the process I think. I certainly had more than one serving a day and it didn't seem to be a problem. However that was a couple of years ago so things may have changed. Enjoy it! I remember really liking the SF jelly and used to have a pint at supper - probably not ideal though.
