Hi there,this is my first time on here too !After years of opiate induced chronic constipation ( 240mgs morphine sulphate per day )and that old set like concrete feeling I decided that last week I would stop all the laxatives that I have been taking ( lactulose, movicol, bysacodil, syrup of figs, senna etc ) and a myriad of other remedies that really hadn't worked if at all and try something else.I had regularly been washing out with warm soapy water after about 5 - 6 days of food to remove the blocks of iron that were in my bowel as this was my only real way of getting things at the tail end moving and out. As you can imagine, sometimes this was taking up to 2 hours of holding water in and hobbling about ( cannot walk very well) and praying that my stools would empty and that I could feel some relief from the agony!Well, I had been getting a swimmy head and my heart would also race and generally a weak, jelly like feeling all over but not for very long, in fact the wierdest feeling when larger stools came out.I have very high blood pressure and wondered whether that might have something to do with all this ??All the best John
