Absolutely no danger of overdosing on the stuff.  Thiamine is nontoxic, and safe.  I had gotten to 1000 mg of Thiamine HCl a day at one point.   Do continue taking the multivitamin with the other B vitamins.  You may want to add a magnesium supplement because magnesium and thiamine make enzymes together.  I like Magnesium l-Threonate (Neuro-Mag by life extension).  You may want to add a B Complex in addition to the multivitamin (take them at different times).  All the B vitamins are water soluble.   With Thiamine HCl, there's a "magic moment" about 500 mg, where sufficient thiamine can get into the cells by passive diffusion, and the difference is amazing.  In...

She says it hurts when she wakes and then other random times during the day.  We are SO strict with her food. We don't eat out, out whole house is gluten-free. I make everything from scratch. She eats very healthy. She's not picky and we do tons of fruit...
