We've investigated ketamine treatment, which does indeed sound very interesting. However very few clinics here that offer it, though it seems to have improved recently. Definitely will follow up on this.
There’s lots popping up now though. Even in Canada I thought we’d have trouble getting support from our family doctor but she was actually supportive so now if we look to do any more can just get referral from the GP here and do it in toronto.
Definitely do hope you give it a try, might be just what your SO has been looking for. Also seriously don’t discount the weighted blanket!
No promises it'll help, though. But hope feels good by itself sometimes.
