Oh Gosh Tam!... you poor dear...

getting all blocked-up is not fun ...

Hope that you get relief real soon (like yesterday! )...

I think its OK to take laxatives if you are on meds that block you up...
I would suggest you take turns of different ones instead of sticking to one sort always, some are more gentle and natural than others, some are just "lubtricants" others are "bulk formers" and then theres "softeners" ...ask your friendly Chemist person for advice .
