I just want to say keep it up, your about done with the worst of it, seems like your holding up quite well, I want to just add in a little hunk of my day to day life as of lately and how I've been managing myself.
First off if the doses I take aren't a guide on how much you should take (as I'm sure you know ;p). Anyways I swear by Immodium, loperamide has been a huge HUGE help in my life for awhile now, I first started around 36 to 48mg and now have to take 144 to 288mg. If you take the route of Loperamide please remember that as much as it may help taper down ever couple of days. Obviously I did not take my own advice lol. But start at a dose you feel comfortable with, and give it about 2 hours till it starts to kick in, after that time passes if it hasn't helped yet you may take more of you feel obligated, I will say it does help, in fact imo it helps me more then bupe ever has. I still have regular bowl movements(although I do have IBS and Lactose Intolerance), the only downfall is occasionally, if I don't stay hydrated I do get a headache, some days i get blurry vision and a dry mouth that feels like I'm sucking on a sham-wow pad ha!
BEST OF LUCK TO YOU, you can do this it's not as impossible as it may feel.
P.S ditch the alcoholic, abusive husband dear, I don't know your story and it's not my business to be poking my nose into, but I watched my mother being abused for 15 years. Nobody should ever have to endure living that life, trying to love, or being in love with somebody who cares more about a bottle of booze then a kiss from their wife..
