Hi and welcome to the GERD forum.
The one med u r on Wellbutrin also known as bupropion...this med can have side effects that u should talk over with ur Dr.
What are the possible side effects of bupropion?
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.
Anxiety itself can feed the reflux symptoms to flare....so talk with ur Dr about getting the med possibly changed...then also talk about other changes u can make to ur diet and lifestyle to help the meds reduce flare ups of reflux.
