Not a nice subject WARNING Gross.....Constipation 1 week out

 You said you already take magnesium.  How much and what kind.  I take the kind Vitalady recommends, magnesium oxide 500 mg twice a day.  I also take Miralax (generic) daily, as well as fiber and probiotics and I haven't had much of a problem going on 2 months.
Good luck to you.  I know how miserable it is.  I gave myself a hernia from straining.  That is when I knew I had to find a routine that worked.
When I would get desperate I would use milk of magnesia, enemas and suppositories.  I was close to going to the ER so I know how bad it is.  Impactions are the worse.  I got those when I took ground flax meal so now I am careful with it and only use a bit.

I take 2 -4 colace a day (100 mg each)  miralax in my AM protein shake and magnesium as well.  Sometime I add a second dose of miralax in my evening shake if I have not gone yet.  For awhile there I was pretty regular but then I back off the routine and am having a problem again. So even once you feel better keep doing what you are doing to stay regular.

 Milk of Magnesia...works like a charm..it's yummy and it's not fiber...fiber will only constipate you more at this time...you need to get the stuff out from both ends...in other words take Milk or Magnesia and then do some laxative supositories one day and an enema the next...Fleet....very nice....

miralax will not UNconstipate you ...nor will fiber...once you're stopped up the fiber and all that just packs in on top of the poop that's already in there....you have to clean out and then start again with the fiber when you are cleaned out....so good luck... 

You have to use a suppository at this point...I feel ya, im still struggling with this problem and can't find a routine that works for me..

The magnesium supplement I take has these ingredients,

Magnesium Oxide (Magnesium 320mg) 530.7mg
Manganese sulfate monohydrate (Manganese 5mg) 15.4mg
Pyridoxine hydrochloride (vitamin B6) 50mg

I only take one per day so not sure if I should increase this to two of them?  Some actually came away this morning but I can still backed up to the eyeballs and it's making me feel quite miserable. I aso took late yesterday a couple of Senna tablets which contain 8mg of Sennasoide leaf which is supposed to be a natural softner.  Something has to work.

Miralax saved me TWICE after surgery but I had to take double doses over two days to get it to work as I was so messed up.  Keep trying it.....pray you are better Karin!  I will NEVER forget what misery I was in.

Good luck!
