I just renewed the prescription and the instructions say the bottle of 40 1.0 mg pills must last one month so he's trying to cut me down on it. That's fine as I don't want to get addicted but this seems somewhat extreme.
You won't become addicted, but if you've been taking 1.5mg of Xanax daily for 2 months you may have developed a physical dependence and will probably need to wean of it. This will be true of Lexapro too. Dropping the afternoon dose probably wouldn't be too difficult normally, but doing it while starting Lexapro increases the degree of difficulty. It may be better to hold off until the Xanax kicks-in, but that could take a couple of months.
I'll try and cut down but don't want to try and look into buying it online. I'm sure that's illegal anyway and those sites are scams.
Benzodiazepines are scheduled drugs and in some jurisdictions possession without a prescription carries similar penalties to possession of opiates, so that definitely isn't a path you want to go down.
Any thoughts appreciated.
Benzodiazepines are no longer good primary, taken daily anti anxiety meds, not because they don't work, but because doctors are increasingly reluctant to prescribe them so getting them in the future is becoming more uncertain. Therefore the sooner you get onto a therapeutic dose of an antidepressant and off the Xanax the better. While it is likely that you could wean off the Xanax now with minimal difficulty because of the short time you've been taking it, this will become more problematic as time goes on. Switching to the long acting diazepam (Valium) and weaning off it will then be the easier option.
ATM, I think you need to discuss all this with your psychiatrist asap to formulate a plan for getting you onto an antidepressant and off the Xanax.
