Vitamin content symptoms and conditions

I was prescribed Doxycycline for chronic prostatitis. I took 100mg. twice per day for 3 months. The doctor told me that he puts men on antibiotics (Bactrim and Ciprofloxacin) for 6 months and longer. I had been on both of those drugs in the past and had depression after taking ciprofloxacin for thirty days. I have not had depression from the doxycyline "yet" but did experience insomnia and minor dizziness off and on for a month before the serious effects hit me. During the course of treatment several times I felt unusual tiredness for a day or two but it would go away and I would feel strong again. One week before I stopped taking the doxycycline the bad effects started. Lower back ache, humming in the head, loud ringing in the ears, mild mental confusion, forgetful, headache, dizziness, lack of appetite, nausea, minor tingling in the upper lip feet and hands, sore anus, minor pain in the throat, unusual tiredness, scratchy eyes (like sand in them), redness of skin, pale hands and feet, joint and muscle pain, tight muscles in legs, bloating, abdominal pain, and blurred vision. I have been off the doxycycline for four days and still have many of the symptoms. I read at ****** that doxycycline depletes the body of B vitamins. The week I stopped taking a multivitamin / mineral pill the symptoms started. I was very cautious about taking the vit. pill four hours after taking the doxycycline throughout the course. I plan to get a blood test to confirm the B vitamin content. I took a vit. pill today and it has helped reduce the insomnia and color of the feet and hands. My question to you all is how long dose it take the body to repair the damage? Thank you for all your posts they give hope of recovery.
