These crackers taste absolutely delicious, but leave a coating/aftertaste in my mouth that lasts for a long time. Also, they contain MSG and for some people (I'm one of them) it causes a headache. The last time I binged on these crackers (and they are hard to put down!), I ended up with a crashing headache. Be forewarned!
