Omeprazole and antacid

Having been on omeprazole on and off for 15 years I have finally come off it.
My Gerd symptoms were worse at the end of the working day, probably due to me being a dentist, not an ideal posture for a Gerd sufferer. I could control my symptoms with 10mg daily but still got occasional side effects. The main one was slight diziness/ visual disturbance esp with bright light.
Have been using DGL 20 mins before my evening meal and just take magnesium hydroxide based antacid at night if required. Feel it is better to let the bodies natural buffering sort out the acid-base balance.
It has taken 3 months of cold turkey and the odd bout of severe symptoms but seem to be coming out the other side and now have several days at a time with no symptoms at all.

I have been taking Omeprazole since December 2007 now so 2 and a half months.

I had the dose increased to 40mg 3 weeks ago as 20mg wasn't curing the burning in my throat.

For a few weeks now i have had increasing vertigo/dizziness and palpitations. I only linked the 2 to the medication just yesterday, googled it just now and confirmed my suspicions to the Omeprazole.

Other feeling i have had since taking this medication...

Severe dizziness
vertigo
palpitations
headaches/migraines
weakness
fatigue
sweating
nausea
bloating
stomach cramps
visual problems
intolerance to bright lights
aching joints
chest pain

Now my question to myself is do i come off the tablets and endure the misery of my acid reflux? surely there must be something else we can take for our stomach problems that don't cause these awful side effects.
Anyone tried anything else that worked and didn't make them unwell?
