I've tried to explain dude, but my GP flat out refused to offer any help, other than "here's a support group you can talk to about your substance abuse".
God bless the NHS.
I had exactly the same problem, also stemming from etizolam. My GP was very hesitant but was ultimately instrumental in me getting a long taper.
I basically had to register with the support group/recovery partnership before they would get involved. The support group kind of monitor and advise, and I'm not sure a lot of GP's really understand, especially when it's an RC benzo. It also indicates that you're serious about coming off, and not just looking to score some free benzos.
Initially my GP flat out refused and said I'd have to go to the hospital, who gave me a strip of 2mg diazepam. I also had to register with the recovery partnership. They are pretty clued up and deal with this stuff more than your average GP (my GP hadn't dealt with benzo users since the 90's). The recovery partnership should make it happen; I think that GP's might also just like the reassurance as it can be quite stressful getting involved. If he tried to stop me now then he'd have to deal with some geordie wifey battleaxe i.e my 'recovery coordinator', giving him an absolute bollocking on the phone. For the record, I really didn't want to go, but I guess it has been helpful.
Urbain, I really suggest getting yourself to A&E and saying you're withdrawing from benzos after discontinuing use, and you've been experiencing twitches and brain zaps throughout the day, which you've read may be indicative of a seizure. A small white lie, but it is a medical emergency, and you can't be risking a seizure or long term withdrawals just due to ignorance or fear. Push for a long term taper and avoid the myriad of issues. There's no need to risk damage/relapse.
By the way, I found it a lot easier to just say I'd been using diazepam or xanax in the end. Trying to explain etizolam was just far too complicated.
