If you have used it before and it's not tough, you should use it everyday. It has shown to be very beneficial in MS patients and it's pretty safe. My cousin takes 400mg a day and his lesions are decreasing. He started at 200mg a day and it was tough at first for him. After 6 months he increased to 400mg (200mg twice a day) and thats when he started feeling better. He does the antibiotic protocol (wheldon protocol) and has greatly improved. Glad you are improving, you might want to ask your doctor about Minocycline or research it yourself on this forum, especially if you have taken it before with no problem. Many people use this for pimples for years and years so it's very safe, cheap and effective.
