I Occasionally Have Issues Where I Wake Up In The

i occasionally have issues where I wake up in the middle of the night because I have regurgitated a small amount of bile up into my mouth. This usually is followed by a long period of not being able to rinse the taste back down, some mildness soreness or burning in my throat, etc. Is this acid reflux? Is there something that I could take to prevent this from occurring (especially if I were to eat acidic foods)?
