Welcome to NeuroTalk:

I see some glaring problems right off the bat....

1) reflux medication depletes many nutrients that are dependant
on acid in the stomach to get absorbed:
B12
folate
calcium
magnesium
iron
zinc
some trace minerals.

2) 40 mg of any statin is alot...and very damaging. Every day we get new information on how statins hurt nerves. Just this week, an article in Science Daily showing in photos nerve damage:

Anyone taking a statin has to supplement with CoQ-10. This vital nutrient our livers make, is blocked by statins so that the mitochondria in our muscles and nerves cannot make energy anymore. So right off the bat you need to do this first!
There are new versions that have be solubilized chemically to be absorbed better. Qunol is one and affordable at Costco and WalMart. Another is Q-Gel...available on line. If you use this type 100mg a day is enough for most people. If you choose an oil gel cap type with soybean oil in it, you'll need at least 300mg a day.

Next up in priority is magnesium. You need this because of your reflux drug. Most Americans (up to 70%) do not eat foods that supply this essential mineral. Taking that drug besides, makes you very vulnerable and very potentially low.
Magnesium can be had orally with a good supplement called SlowMag... one twice a day (available affordably at WalMart), and also can be used topically or with epsom salt soaks...to your feet. Topically there is a nice new lotion made by Morton, called Epsom lotion, and it is so far very new and on Amazon ($7.98), or at WalMart (again)... for $5.98. I try to find the most affordable quality things for people here and for myself too.
WalMart has been a savior of sorts for me in this regard.

Get your B12 tested at the doctor's and get the numbers for the result. Then supplement if you need it (400pg/ml or lower).

You can think about lipoic acid and benfotiamine too, but these others should be first because of your history and lifestyle.

To get the best results here, there is no substitute for reading the Subforum above, the B12 thread, and other posters questions. You will find yourself already on this forum, thru the words of others.
