He’s Trying To Quit And I Want To Help!! Serious Answers Only!!?

Okay, my bf is trying to quit smoking and doing drugs at the same time. So now he’s going through withdrawal– headaches, feeling sick in the morning. How can I help him? We can only talk through MSN for the next 2 weeks… and what can he eat that will be fine when he’s feeling sick?
We don’t have the money to afford going to detox right now and it’s marijuana by the way– a long time of it, but he’s strong and I know he’ll pull through on his own!! No need for rehab/detox.. or anything like that (which we can’t afford!) I don’t know what to do! I tell him im proud of him, i ask how he’s feeling and listen to him when he needs to talk! i I dont know what else to do to make this easier for him!!
This is a serious question and i dont appreciate your stupid comments.. thanks to those who actually TRY!

I Get Sick To My Stomach After I Work Out Hard, Is This My Body Detoxing From Smoking?

When ever I go to the gym i sweat a lot and when I get back home my stomach starts hurting so i can’t really eat much which is bad because I’m trying to gain weight. I’ve been smoking marijuana for the past year everyday but I’m trying to quit, do you think my body is detoxing from the THC and thats what is upsetting my stomach? Also another thing I can’t eat much when I’m not high, its a kind of withdrawal symptom but my stomach doesn’t really hurt, only after I workout.
