Hey people, I'm glad that I found this posting myself! I've battled depression/anxiety for the past couple of years but thought I had gotten. Then I was Rx'd doxy 100mg twice a day for my cornea in my eye not working based on a clogged gland. Since I've been taking it I have been sick to my stomach (OK I new that was coming) and have had hot flashes and sensitivity to light (didn't see that but OK), and yesterday I felt totally detached from rational thinking. I felt nervous all day, was a bit light headed, and battled a bad case of depressive thinking. Today has been a bit better but I worry about this feeling returning. I need to continue taking the meds for I need to be able to see clearly. Has anyone else felt 'nervous w/hot flashes' while on doxy? I'm also taking fish oil omega-3 but it hasn't ever affected me like that.
