I'm at the end of a 10-day cycle of doxycycline (100mg 2xday). Worst side effects: insomnia and restless leg syndrome. I think I'm averaging about 3 hours of sleep a night. Stomach pain, occasional cramps, severe loss of appetite. I've also experienced some of the stranger side effects others have mentioned: mood swings, depression, suicidal thoughts, feeling like I'm in a dream, mental problems (after I write something I realize I've spelled half the words wrong). Next time my doctor mentions this drug, I'm going to say no way and see if I can get a sulfate based antibiotic or maybe good old amoxicillin.
