I started taking ephedrine (ephedrine sulfate) (legal here) 2 weeks ago. now i have crazy migraines whenever i miss it (for days). how can i wean off w/out bad pain?

Reduce dose slowly: Good idea to get off Ephedrine (ephedrine sulfate) - it is dangerous in the long run. I suggest cutting the pills in quarters and taking 3/4 a pill daily for a week and then cutting to half. If you still get the symptoms on cutting to 1/2 after a week, then stay on 3/4 for another week and then try again. Caffeine may help relieve the headaches too. Hope this works for you. If not let me know. Good luck!
