I know mebeverine is an antispasmodic. As for colifac... I had never heard of it, nor can I find any conclusive info on it (in english).
Isn't your problem bloating and constipation? I'm not sure an antispasmodic is what you need. You made need something like anti-gas pills and/or a laxative, like Miralax.
Have you spoken to your doc?
