Hi spuddleduck
Just wanted to say I sincerely hope you're doing OK as you read this. I too had an extremely similar reaction to NAL to yours on my first day, as I described in a thread in this forum:
viewtopic.php?f=5&t=2321But 6 weeks on, I am OK. I've got sick only once since the first day. I initially took 12.5mg, then gradually moved on to 25mg, and now on 50mg without virtually any side effects. I was very careful not to take NAL and drink with an empty stomach in the first couple of weeks. But things are much better now. Amount-wise, I drink about a half of what I used to drink before NAL. Still early days, but I am positive about the outlook (and it's extremely unusual for someone who is so 'glass-half-empty' as me - and actually my glass tends to be still half-empty these days when I've had enough

).
Hope your condition gets better and stable soon. And hope you have a medical professional around you in case things get tricky! Look after youself!
