Venlafaxine for ADHD week 1. : Effexor

First week. I’m trying to get off of stimulants right now. I have been working out and using pre workout. I had a “brain cramp” for a lack of a better word. I stopped taking Focalin and it hasn’t happened again. I thought I was having a stroke. 😬 I like the lactic acid thinking I get after workout but it doesn’t last though the day. For whatever reason I’ve been treated for about 10 years with 1 year of this journey being all over prescriptions wise. Tried guanfacine, stratera, propranolol, hctz, for non stimulants. Tried Adderall , Ritalin, concerta, and focalin. Focalin worked the best but the insomnia is a no go for me. I’ve been on venlafaxine 37.5 for 1 week. I’m much better with impulsivity, anxiety, freak outs, and social situations. I have had a headache for the last day and nausea every time I take it. I haven’t been reckless with eating like I usually am. I can’t drink etoh though so hanging out with friends is weird without social lubricant. Anyone else been treated and what to expect further? I think it takes like 3 weeks?
