If you attend the Holy Sacrifice of the Mass out of hte motive of pure love of God, you cannot attend too frequently. But - communion only twice per day - it is not like taking vitamins - it is spiritual food which can last for all eternity.
There are some who attend out of superstition, out of OCD, out of love of the magesty of it all, or other reasons. Best to avoid lapsing into something like that, as it can become an empty gesture.
But, for love, now you are talking!
