It is impossible to tell, but that doesn't matter right now. What matters is that you have relapsed in your depression, and you need to see your doctor ASAP for a medication review and re-evaluation. Since your depression was well-controlled on the 300XL (without the clonazepam, I think a good place to start would be to return to that plan and make adjustments as necessary.
In the meantime, you need to call your doctor and let him know how poorly you are feeling. Don't let this wait any longer!
Good luck, and please click ACCEPT if this information was helpful. Thanks.
The wellbutrin should be the same, but it is reaching different levels in your body because of the dosing schedule. This is possibly the cause, but I doubt it.
I think the Klonopin is more likely the culprit here, and your doctor will likely stop it. If your anxiety is still high, there are other medications to try.
