been through this, my g/f made dinner because hell have no energy and be miserable and wont want to make anything to eat.... and if you make something he probably will eat some.... dont crowd him because that will make the restlessness go crazy (it did for me) . if you sleep together it might be hard on you because its pretty darn hard to sleep when your in w/d.... just support him... and honestly for me sex was probably the best thing she could do for me.... takes the mind off how crappy you feel and seems to help relax a little lol......anyway hope this helps a bit!
Ashley..alot of ppl suggest "the Thomas recipe" google it. Should help. Also be very supportive as he will need someone there for him. Sleep aids help with sleeping too. Good luck. Feel free to ask more questions.
How much has he been taking?
Welcome Ashley - click on my username and go to my journal for withdrawal - I wrote a really detailed bit about my experience and things that help - its too long to post here but basics are: Gatorade - HYDRATE him, Immodium - SUPER important and give it to him aggresively, lots of hot showers and just help him through this. Try not to hover too much - he may want you close or he may not - don't let this hurt you.
When we withdraw our senses are overwhelmed and sometimes just laying alone in a room to cold sweat it out is all we want. Everyone is different. Go read my journal entry - it'll give you a lot of info.
Best of luck!
