Fish oil 1000mg symptoms and conditions

I have been on 40mg/day of Lipitor for 5-6 months and this is how I feel: totally drained - no energy at all - horrible lower back pain - I've been in physical therapy for the past 6 weeks. My neck muscles, back muscles and hip muscles were in constant spasms. Right after beginning Lipitor I woke up with vertigo and still have the dizziness. I was convinced that I must have some horrible disease and was dying at age 47. I stopped taking Lipitor 3 weeks ago and starting taking fish oil, vitamin c, coq10, b vitamin, daily vitamin - the muscle spasms are a little better - still have lower back pain, brain fog, some dizziness. I am so tired all the time - it's so difficult to work a full time job right now. Has anyone else had these same symptoms? Does anyone know how soon I should start to feel better?
