"i have been on this med 4 days now. the first day i made the mistake of taking it night before bed, boy was that s mistake! up all night really bad insomnia. day 2 i took it in the afternoon when home from work at 2 pm. i curled up on lazy boy and did not want to move, ended passing out due to pure exhaustion, needless to say i did not get up till the next morning 15 hrs later. day 3 about 1 hour after taking developed slight nausea and the feeling of extreme skin sensations like things crawling on me , but those do subside after about couple hours. on 40 mg and going to stick with it and ride it out for a few weeks to see is side effects lessen. also on 450mg of wellbutrin at the same time. i think it is working in a weird kind of way!!"
