I have successfully weened myself off amitriptyline. Its has been three weeks now (doesn't that sound like I'm in AA?). The damage was minimal. I took two days off as I had a severe migraine and then a normal headache the next day which is very different to a lot of time off when I weened myself off painkillers!
Yes, I'm still getting headaches and migraines - I generally know why I get them. On Saturday, although I didn't sleep in (oh remember those days when I was allowed!) I missed breakfast and had a bad one that evening.
I'm just so feb up of medications, I'd rather just get on with it. There are people suffering worse than me.
