you clearly don't know what you're doing.
First: AI 'when needed' is wrong. AI's are meant to keep your estrogen at a particular, consistent, level. If you're not using it consistently, you're using it wrong. This was a big mistake. Unless you're getting bloodwork multiple times a week, you have no idea what 'as needed' would even mean.
Second: You used WAY too much nolvadex. You should have been using 20mg/day at the most. I would immediately lower the dose to 20mg.
