just got back from the ER...Sulfameth for 3 days now...totals 6 pills...can't sleep, nervous, dry mouth/white coated tongue, muscle cramps, nausea, general sick feeling...also was taking Buspar (anxiety) and Aciphex (heartburn), and also Reglan (anti-nausea)...made a major mistake by downing some sleeping pills (Walmart brand and a Nytol)...haven't slept more than 15 minutes in 3 days...right now, I'm "clean" for almost 24 hours...smoked a cigarette, having a beer and calling it a day (or three)...I'd recommend you SERIOUSLY talk to your doc about alternatives to this one...hadn't had any problems before taking it...already feeling better...have been drinking water all day to flush this stuff out...
