THIS IS MY 8TH DAY ON LAMICTAL 25MG AND I WOKE UP SO DIZZY THAT I ALMOST FELL OVER. I HAVE BEEN THIS WAY ALL DAY IT LIKE COMES AND GOES FAST. IM DIZZY NOW.. I HAVE NOTICED MUSCLE ACHES BUT I THOUGHT THAT IT WAS THE ATENONOL 25MG I TAKE FOR PALPITATIONS BECAUSE IT LOWERS YOUR POTASSIUM. IM THINKING THE LAMICTAL DOES THE SAME LOWERS YOUR POTASSIUM WHICH CAUSES THE MUSCLE PAIN AND ETC.. SO I BEGAN EATING BANANAS AND SEE HOW THAT GOES. MY DOC SAID THAT IF YOU TAKE A ANTIDEPRESSANT AND YOU ARE BI POLAR YOU CAN HAVE SERIOUS REACTIONS TO THE MEDS. SHE TOLD ME TO "NOT" TAKE A ANTIDEPRESSANT. I WAS ON THIS MEDICINE BEFORE AND WAS UNSURE ABOUT A SIDE EFFECT OF ULCERS IN MY MOUTH AND STOPPED IT. I REALLY WANTED TO CONTINUE BECAUSE IT MADE ME FEEL GREAT(only got to 50mg then) I HAVE ACTUALLY FELT PRETTY GOOD MORE GOOD DAYS THAN BAD EXCEPT YESTERDAY AND TODAY I HAVE BEEN REALLY TIRED ALONG WITH THE OTHER. MY QUESTION IS WILL THESE SIDE EFFECTS GO AWAY???? AND I DON'T WANT TO REALLY EAT MUCH. I REALLY LIKE THAT I AM NOT MOODY ANYMORE LIKE I WAS AND I GOT MY SEX DRIVE BACK AND I DON'T WANT TO GO OFF IF I DON'T HAVE TOO.. HOW LONG DO THE SIDE EFFECTS LAST?? AND IS IT WORTH STICKING IT OUT?
