Your original sentence is fine, this is just a stylistic suggestion to use a more commen phrasing (in my opinion).

Because you "sometimes" "used to" get a headache it means you got it (them) multiple times. So you should say "my headaches" (plural) even though its okay to say "I used to get a headache when ______" (English plurals are so weird, I know ㅠㅠ). Just remember that the "sometimes" and "used to" part means it happened more than one time, so you need to say "my headaches" (plural) here :) Also!! You can say "Since then, my headaches have calmed down." Your sentence is totally fine, but personally I would write it in this form instead, just because it sounds nice to me. You can keep your original sentence if you prefer it! ^^

(This was a tricky one, I think my correction works)

When I had troubles bydue to having no space for keeping the books, my brother recommended When I had troubles due to having no space for keeping the books, my brother recommended

You can say "due to" or "because of" or even "caused by" here. They are all roughly the same in this situation. You can also say: "When I had trouble (with) finding space to keep the books in, my brother..."

When I had troubles byfound I had no space keepingto store the books, my brother recommended When I found I had no space to store the books, my brother recommended
