gawd this stuff... much as it is helping the panic attacks, i have to be so careful when i take it - at least 2 hours after dinner, and no later than 8pm - or i don't get any sleep by night and am a zombie by day. if i have an empty stomach i get a bad stomach ache. if i eat too much or too close to taking it, i am sooooooooooo sick and feel like i'll lose everything i ate. naturally, the past 2 nights i took it too late... kiya zombie at your service - that is, if i can keep my eyes open long enough.
