Quick update - well I took my first Nalmefene tablet yesterday and this is my experience:
Took the tablet at 5pm (my witching hour usually starts at 6pm whilst cooking dinner). I then headed out to the shops and thought I would treat us (just me and hubby) and bought a couple of steaks and decided to make dauphinoise potatoes to go with it - and of course a bottle of wine. I usually buy two (one's never enough - luckily hubby doesn't drink wine so I know I don't have to share

!) but thought I would try to lower my intake last night.
Well - by the time I got home just before 6pm I was feeling a bit 'indifferent' - not sure if that's how to describe it, but I truly didn't feel like I could be bothered to do anything - my enthusiasm to cook the lovely meal I had 20 minutes before had left me completely (this is so not like me!). I said to hubby that I was going to sit down and read for half an hour and would call him when dinner was ready. I didn't even feel like drinking a glass of wine, but felt I should as I'd taken the tablet. Well I drank it really slowly, didn't enjoy a single sip (this is my favourite wine - but it just tasted like vinegar). I was ragingly thirsty, so also downed a pint of water.
I cooked dinner, but felt totally indifferent about eating it. It was weird. I had hardly eaten anything all day and was quite hungry, but when it was served up I just couldn't eat more than one mouthful (this is not like me at all!) I drank lots of water, but started to feel quite unwell (sweating, heart felt like it was racing and quite sick). So I went to bed.
I wasn't sure if what I was feeling was alcohol withdrawal (I usually drink two bottles of wine a night - and I'd only had one glass) or whether it was a side affect from Nlmefene. I felt really unwell all night - kept dosing and then waking suddenly feeling as though I had forgotten to breath and gasping for breath. My heart was pounding so fast I thought I was going to have a heart attack - I was so relieved to wake up alive this morning!

It's now almost 2pm and the feeling of wanting to be sick is only just starting to lessen a bit.
I know most people are taking Naltrexone - but I understand that these are basically the same drug. Has anyone else experienced side effects like this? We are going out to a comedy night tonight and I've decided that I will be AF - I simply can't risk feeling that ill again tonight. Can anyone advise how long these horrible symptoms will last - I'm terrified to take the next tablet.
Oh - on the plus side - I haven't thought of drinking all day - and the thought of having a glass of wine tonight makes me feel positively sick. I don't think being AF tonight will be a problem!
