absorption of medication problems NEED HELP

I am having some problems absorping some of my meds after being almost 5 yrs out. I heard somewhere a long time ago that there was a way to test meds in water to see if they were soluable. If ANYONE knows anything about this please let me know ASAP. I'm really in trouble here. Thanks!

which meds? are they time released or packed in oil?

if you want to test the break down of the "vehicle", you can put capsules in your mouth directly, roll them around til they get soft, and send 'em on down.

I'm not brave enough to test tablets this way, so I rinsed my (clean) mouth in water 4-5 times, like 1 oz? So, I had thoroughly saliva soaked water and put my tablet in there.

Now, for example, if you are taking Rx vit D, the "shell" will break down immediately, BUT it's D2, IN OIL. We only absorb D3, deliver in dry form, so capsule with powder.

I take Welbutritin, but rather than XL or SR, whatever it is, I take 100mg 3 times.

This is amazing. I thought I was going crazy as to why some days my meds would work and then some days they wouldnt. I take Wellbutrin XL 300 and some days it is awesome some days not. Im 6 years out. So, I should ask for another type?
