insomnia
"I suffer from high anxiety and manic depression. I have had trouble getting to sleep for years and sometimes would go days without sleep causing insomnia on top of everything I deal with making me feel like I'm going nuts. After being up 3 days straight I broke down told my doctor I needed something to help me sleep and be gave me zaleplon. I thought sure why the hell not, worst thing that could happen is it doesn't work right? Turns out it not working was the worst thing that happened. Not only did the crap not work but I stayed up a 4th night waiting for it to make me tired. I might as well have taken nothing. At least with nothing you're not anticipating things that won't come. Man, benadryl works better than this. Waste of time and money"
