Magnesium based laxatives often work. They bring water into the bowel and soften things up some. They may also be absorbed a bit as well. Magnesium citrate is the most common one used. Read your labels carefully.
Metformin lowers B12 levels in about 40% of people using it.
And Nexium blocks the absorption of these nutrients:
B12
folate
iron
calcium
magnesium
zinc
That we know of so far.
So you may be low in B12 and that is hampering things. Many people on metformin have the opposite problem (diarrhea), so you seem to have missed that side effect!
Chronic use of cascara products (which contain Senna) is also not recommended. It is implicated in bowel cancer. Occasional use is okay, but not everyday, or many times a month.
