G.G,
Okay, sorry...but I would rather over react than under, so I just want to make sure you are safe!
Even if you are not in crisis mode...you still should consult with your docotor's on-call stand in. He or she can advise you on how to proceed.
We can't make a recommendation for weaning, as only a doctor should do so...
...but wish you the best in getting the help and answers you need. Please keep us updated as to how you are doing. We understand and care!
S.C.
