Regurgitation symptoms and conditions

I have been experiencing a flu like symptom for over a year now. They started about 2 months after I began taking 350mg of lamictal a day. Symptoms include exhaustion, headache, soar/achy throat, post-nasal drip, TONS of nausea, lack of digestion & regurgitation of food. I am tired and feel warn out all the time... I have had everything checked by doctors and they've found no health reasons to explain these symptom's.

HAS ANYONE ELSE EXPERIENCED THIS????

I have been having a hard time with this med for a long time and now I have had enough. I noticed when I first started taking this med for high blood pressure, and this is the first med I ever had to start as a regular daily medication, that if I didn't make it to the bathroom immediately I felt as though I had to vomit and had a strong regurgitation response and it lasted until I emptied my bladder. I feel that over time this is a huge side effect and at times I have felt a prisoner of my home by way of fear of not having a bathroom close by quick enough.
