hey trimmer.
my SO is on day 2 WD from Oxy. Almost day 3. i'm proud of him.
one thing i might throw in here, stay away from take out food. try to eat things with no preservatives, or do some simple home cooked things. nothing too big, but...the more natural the better. flush with fluids all you can. take a multivitamin every single day. and try tea to help calm your stomach. also, keep the immodium handy.
My SO is trying 5-htp (vitamin section) to help combat the anxiety, and a melatonin/valerian combination to help him sleep. So far, so good.
YOU CAN DO THIS. its hard. but everything worth doing is difficult to get done. just be strong.
