In the past 4 monthsI have been switched from prozac to lexapro to zoloft in additon to trileptal that ive now been taking for 2 months. I was told by my doctor that there shouldnt be any problem doing this and would not take the usual 2 weeks to be effective. So why am i having severe moodswings, a constant feeling of flipping out, panic attacks and now a sunburn type pain a appearance on my face, arms and upper torso that seems to be getting worse.
