Here's the deal, I'm paradoxiccal on every medication. My Pdoc did genetic testing and found that nuvigil would be great. Started nuvigil with lamectal and felt better than ever: free month from pharm co. Insurance denied it until I tried modafinil I wasn't impressed. Started nuvigil 2 months later and it made me sick. Had gas built up in my stomach and felt terrible so started modafinil again. Finally stopped it. I was on 250 mg of nuvigil and 200 of modafinil . I just started back on nuvigil 5 days ago and took a full dose. But now I'm only taking half. I feel weird like lost an tired. Need advise
