I just found out about The Sinclair Method and Naltrexone and this will be my 3rd day (taking pill at 4PM today). I am 57 and have been drinking since in my 20's with the my drinking escalating so much more in the past 10 years, blackouts, really bad hangovers etc.
I am having really bad side effects and hope you can answer and help me with this so I can stay with this. I have ordered the book but will not get it until next week so sorry if this is covered in the book. I took 50 mg for 2 days and feel like I am going out of my mind, anxiety, nausea, shaky, dizzy, drugged, tired but can't sleep and just want to crawl out of my skin. I am very tense and so much so that I am clenching my teeth which either has brought on a headache or it is another side effect.I took my last pill at 4PM yesterday and drank a bottle of wine and then actually felt calmer and slept for an hour then BAM the anxiety all came back. I am sweating more (I have had hot/sweat flashes every 20 minutes or so for the past years due to menopause), when I am not sweating am am freezing cold.
I took drugs to experiment in my teens and this likens me to when I had taken acid and went through a horrendous trip which compares to this.
The first night I could not drink as I felt so sick. I usually drink 1-1 1/2 bottles of wine a night so last night I drank a bottle of wine and felt better then felt really sleepy and slept for an hour or so then I woke up and felt really really awful, The word to describe it is "Hell". I tried doing deep breathing and relaxation as I was so tense, felt so sick, dizzy, confusion but nothing helped so I took 1/4 of a Clonazepam pill to calm me. That seemed to help enough to get me back to sleep and this morning I felt a little better. I just had 2 cups of coffee and am back to feeling really awful again, shaky, feeling sick and a drugged feeeling. I am thinking of taking 1/2 a dose today??? Please help me as I really want to stay with this, does this happen and does it go away and when???
Now it is 1:50PM and I still feel absolutely awful. As some have said I am going to take 1/4 of a pill today and hope I don't go out of my mind like I have been doing.

Wow, that sucks.

Most of us don't have side effects anywhere near that bad, but a few others have reported awful experiences like this. Most of them reported that it went away, or at least got better. Starting with 12.5mg sounds like a wise idea to me.

Thanks Melissa, I took the 1/4 pill last night and proceeded to drink 1 1/2 bottle of wine to feel better. Not sure how many units that is? Is 1 bottle of wine 5 Units, so 1 1/2 bottles would be approx 7.5 units?
Anyway I also took 1/2 a clonazepam pill to sleep and had a pretty good sleep and night. Woke up feeling shaky still but not sick as a dog like I was yesterday. Maybe it was drinking 1 1/2 bottles of wine cause that would always cause me to have a hangover. Going to stick with 1/4 of pill for a few days and then go up to half.
