Hi Lya,
What you are experiencing is normal. Your body is "addicted" to this drug and it doesn't want it gone. EVERY antidepressant has qualities like this so I'm tickled going back on it is not an option. I hope that goes for all of the synthetic ones on the market. St John's Wort is a good alternative for depression but not at this stage for you. Synthetic chemicals, like meds, have to be removed from your body, they don't just go away. The chemicals that are still in your body will always interact with everything else in your life so you need to keep the other outside stimuli to a minimum.
Omega 3s are a wonderful idea as it is simply food. An absorbable multivitamin/mineral complex to replenish what has been removed is also a good option. Make sure it is pharmaceutical grade. I can recommend one if you like.
Exercise is good. Water will flush a lot of toxins (which is what meds are considered) and the exercise will speed the process. Good principled chiropractic care can speed the process along as well. If you don't have one go to upspine.com and look up one in your area.
It will take time to come off these pills. You may also want to slow the down the process of weaning yourself. Some of these meds recommend coming off 1/100mg a week..... This is all written in the fine print that no one is able to read.....Lya, there is light at the end of the tunnel! Keep plodding!
God bless,
M.
