"taking 50mg. this is my first week. wellbutrin gave me hives and lexapro was nothing more than a sugar pill. my most noticeable side effects:  repetitive yawning on day three and day six. almost incomplete non satisfactory yawning followed with a quick wave of nausea. my first two days i felt really nervous. insides were shaky. very minor headaches almost every other day. my general sense of well being has improved but i am quieter. i am not as vocal as i was. almost subdued, which means less arguing with my fiance. i haven&#039;t noticed an appetite decrease, in fact my hunger pains seem more pronounced. my sex drive was gone to begin with so nothing to report there.  i was in the sun today, noticed a much greater sensitivity to it. dry mouth."
