Hi! After meth hangovers, I called my rheumy and now am to inject .5cc instead of .6, and after 2 weeks if still hungover, then .4cc and I will start Leukovorin 24 hours after meth. I feel for all of you that are so tired and have worse side effects. It's not fun laying in bed and seeing the sun out and you can't go out. Have a good weekend!
