I've been on sub for a week now and it isn't taking care of the pain as I thought it would. Also I am in college and I am very cofused with the work i need to get done .It is effecting my eye sight also.today i am not taking it to see if i am addicted yet.If I can make it through today without going into withdrawls I think I will try to get on methadone to help control my pain or see if the dr will prescribe pain pills of some sort. am i doing the right thing? my dose is 1 8mg in morning and 1 at night. I also notice hand tremors and weakness from sub. will these exist with methadone too?
