Geographic Tongue?? Help!

Hi everyone!

New to posting here. A few months back i noticed I started to get patches on my tongue. At first I thought it was thrush but my dentist told me its not thrush. It has really started to get me down as of recently and im worried something serious is wrong. does anyone else suffer from something similar?

The patches are non painful and come and go. Some days they could seem better but others they can be bad, especially after alcohol. My tongue sometimes seems white as well.

Can anybody please help?? : (

also, here is a photo of my tongue, thanks everyone!
