Crazy mind symptoms and conditions

Male here. I've been taking wellbutrin and lamictal for a number of years. Since I've been on wellbutrin i have these crazy, mind-blowing, super intense orgasms. like nothing I've ever experienced. It last nearly a minute. I cry out so loudly that i have to gag myself with socks so as not to alarm the neighbors - seriously, i'm not kidding. Afterward, my throat is sore, like when you've been at club and speaking very loudly to be heard of the music all night. I'm not complaining. Anyone experiencing a similarly strong effect?

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?
