Aww Kay, really sorry you're suffering. Believe me, you have my utmost sympathy because I suffered soooo much with constipation myself. A couple of tips which may help. For immediate relief....without the stomach cramps that Dulcolax can give, try Microlax. This was recommended to me by Goose (I think) and I swear they're a miracle worker. They work instantly, in fact I don't make it out of the bathroom once I've administered the medication (it's an enema but very easy and pain free to use). The relief is almost immediate and I still have some on standby because I don't ever want the pain of severe constipation again. Give them a go, you won't be disappointed, trust me. I did use Dulcolax but they take quite a while to work but then gave me bD cramps & diarrhoea which wasn't pleasant at all but the Microlax just works instantly to get you moving again.
Second tip is drink drink drink and then drink some more WATER!!!!! Water is the magic solution to keeping everything moving. I know its really hard to drink lots of cold wat when the weather is freezing but I had to adopt the attitude that I had no choice in the matter because if I didn't have a good 4 litres of water on top of my shakes & tea that I'd end up with another blockage. I still find it a daily struggle to drink enough water but I have to force myself otherwise I will end up in pain again.
Really hope you feel better soon....Hugs xxxxxxx
