hmm i'd consider my digestion to be difficult. I'm currently takking around 35-40 25000s a day and don't really have this bloatiness. After gorging i do feel a bit bloated but it's nothing that doesn't pass quickly enough. I was once told many years ago that i had a biafran belly which made me realise that my posture was a bit odd and that i needed to use my stomach muscles more to 'suck it in'
oh and i'd consult people about taking those rennies/gavascon/maalox calcium carbonate solutions as they might absorb/ interfere with some medications - unlikely though a possibilty. Like Rosie said they don't really even treat the symptoms so getting to the root of the problem would be more beneficial than masking it.
As an example i recently noticed I quite affected by indigestion. I only later realised that i was lying in bed watching tv at an unusual angle which was putting pressure on my stomach. When i stopped lying i was free of indigestion.
