i'm in a similar situation. have had cfs and fibro for 10 years now. i've been on amytriptiline for 8 or 10 years until a few months ago. it is astonishing that the drug companies themselves, of course, have nothing to say about how to stop the drugs. i was taking it for fibrmyalgia rather than Depression and had found that stopping previously really brought on the fibro symptoms again. i took at least 6 months to come off it. the last thing i want to do is precipitate some sort of a crisis. so i started by alternating 50mg doses with 25mg doses (you would start where you are) for as long as i felt i needed to. then i went down to alternating 25mg with 10mg. then 10mg with 5mg, then finally just 5mg every 2nd night. like i said, i took many months to reduce the dose. if figured that after 10 years i can take my time and be very cautious.
i also had problems with UTI's and thrush after sex with my husband. my solution was to do a douche with apple cider vinegar immediately following, every time. not just internally but the entire area. this made a huge difference.
i have not figured out the right dosage for me yet either. i started with large doses but found it really knocked me about. am waiting to regain a little bit of wellness before start the Iodine again. i believe that mercury might well be a factor in the cfs so i'm booked in to have the Amalgams removed next month.
for the Depression aspect of the illness i have found that meditation has brought me into a whole new way of being. i describe it as buoyancy. things don't get me down the way they used to. i got to a point a few years ago where i thought well, if this is as good as it gets, then i'd better learn to be happy right now, here, today. i small voice told me that meditation might be the thing but i lacked the discipline i thought was was necessary. i went off and did a 10 day vipassana retreat. hard, but a great way to immerse yourself and really learn some new skills. i still lack discipline regularly but i find that any amount of effort in the right direction has an exponentially beneficial effect.
from one tired mommy to another, hang in there. i wish you luck and strength.
