sulfate is just a salt
of morphine. As far as I know, there's no substantial difference between morphine freebase and its various salts. Like all drugs
, and especially narcotics
, different people react to different doses of morphine. It's hard to say. It depends on your body weight, body chemistry, tolerance, how full your stomach is and more. Start low (20mg) and work your way up in 20mg increments every hour if you're not feeling the effects you want. Since this is your first time, I wouldn't advise more than 60mg. 40mg is probably a good dose but, like I said, it depends. It's ALWAYS better to underdose than to overdose. Be safe.

Edit: I just took another look at the dosages thread and they're saying 10mg is a good starting dose for morphine. In SWIM
's experience, that's a little low but for the sake of safety it might be better to start with 10mg and work your way up in 10mg increments every hour. Also, I just re-read your post and I see it's one single 200mg pill, which is HUGE. What you should do is dissolve it in water and divide the solution into 20 equal doses. That way you can be sure that each dose is 10mg.
